We make the `CDC_GENERATIONS_V3` table single-partition and change the
clustering key from `range_end` to `(id, range_end)`. We also change the
type of `id` to `timeuuid` and ensure that a new generation always has
the highest `id`. These changes allow efficient clearing of obsolete CDC
generation data, which we need to prevent Raft-topology snapshots from
endlessly growing as we introduce new generations over time.
All this code is protected by an experimental feature flag. It includes
the definition of `CDC_GENERATIONS_V3`. The table is not created unless
the feature flag is enabled.

This also calls for renaming the future member of the class and allows

Currently the only caller of it is the batchlog manager itself. It
checks for the shard-id to be zero, calls the method, then the method
asserts that it's run on shard-0.
Moving the check into the method removes the need for assertion and
makes further patching simpler.

Currently drain() is called twise -- first time from
storage_service::drain() (on shutdown), second via
batchlog_manager::stop(). The routine is unintentinally re-entrable,
because:
- explicit check for not aborting the abort source twise
- breaking semaphore can be done multiple times
- co-await-ing of the _started future works because the future is shared
That's not extremely elegant, better to make the drain() bail out early
if it was already called.

Changing the second value of cdc_generation_id_v2 from uuid_type
to timeuuid_type made the name of cdc_generation_id_v2 unsuitable
because it does not match cdc::generation_id_v2 anymore.
We change the type of IDs in CDC_GENERATIONS_V3 to timeuuid to
give them a time-based order. We also change how we initialize
them so that the new CDC generation always has the highest ID.
This is the last step to enabling the efficient clearing of
obsolete CDC generation data.
Additionally, we change the types of current_cdc_generation_uuid,
new_cdc_generation_data_uuid and the second values of the elements
in unpublished_cdc_generations to timeuuid, so that they match id
in CDC_GENERATIONS_V3.
We make CDC_GENERATIONS_V3 single-partition by adding the key
column and changing the clustering key from range_end to
(id, range_end). This is the first step to enabling the efficient
clearing of obsolete CDC generation data, which we need to prevent
Raft-topology snapshots from endlessly growing as we introduce new
generations over time. The next step is to change the type of the id
column to timeuuid. We do it in the following commits.
After making CDC_GENERATIONS_V3 single-partition, there is no easy
way of preserving the num_ranges column. As it is used only for
sanity checking, we remove it to simplify the implementation.
In the following commits, we modify the CDC_GENERATIONS_V3 schema
to enable efficient clearing of obsolete CDC generation data.
These modifications make the current get_cdc_generation_mutations
work only for the CDC_GENERATIONS_V2 schema, and we need a new
function for CDC_GENERATIONS_V3, so we add the "_v2" suffix.
The local node's dc:rack pair is cached on system keyspace on start. However, most of other code don't need it as they get dc:rack from topology or directly from snitch. There are few places left that still mess with sysks cache, but they are easy to patch. So after this patch all the core code uses two sources of dc:rack -- topology / snitch -- instead of three.
Closes#15280

system_keyspace: Don't require snitch argument on start
system_keyspace: Don't cache local dc:rack pair
system_keyspace: Save local info with explicit location

We extend service::topology with the list of unpublished CDC
generations and load its contents from system.topology. This step
is the last one in making unpublished CDC generations accessible
to the topology coordinator.
Note that when we load unpublished_cdc_generations, we don't
perform any sanity checks contrary to current_cdc_generation_uuid.
Every unpublished CDC generation was a current generation once,
and we checked it at that moment.
In the following commits, we replace the
topology::transition_state::publish_cdc_generation state with
a background fiber that continually publishes committed CDC
generations. To make these generations accessible to the
topology coordinator, we store them in the new column of
system.topology -- unpublished_cdc_generations.
If a test isn't going to use task manager or isn't interested in
statuses of finished tasks, then keeping them in the memory
for some time (currently 10s by default) after they are finished
is a memory waste.
Set default task_ttl value to zero. It can be changed by setting
--task-ttl-in-seconds or through rest api (/task_manager/ttl).
In conf/scylla.yaml set task-ttl-in-seconds to 10.
Closes#15239
Right now, the function allows for passing the path to a file as a seastar::sstring,
which is then converted to std::filesystem::path -- implicitly to the caller.
However, the function performs I/O, and there is no reason to accept any other type
than std::filesystem::path, especially because the conversion is straightforward.
Callers can perform it on their own.
This commit introduces the more constrained API.
Closes#15266
On boot system keyspace is kicked to insert local info into system.local
table. Among other things there's dc:rack pair which sys.ks. gets from
its cache which, in turn, should have been previously initialized from
snitch on sys.ks. start. This patch makes the local info updating method
get the dc:rack from caller via argument. Callers, in turn, call snitch
directly, because these are main and cql_test_env startup routines.

"experimental" option was marked "Unused" in 64bc8d2f7d. but we
chose to keep it in hope that the upgrade test does not fail.
despite that the upgrade tests per-se survived the "upgrade",
after the upgrade, the tests exercising the experimental features
are still failing hard. they have not been updated to set the
"experimental-features" option, and are still relying on
"experimental" to enable all the experimental features under
test.
so, in this change, let's just drop the option so that
scylla can fail early at seeing this "experimental" option.
this should help us to identify the tests relying on it
quicker. as the "experimental" features should only be used
in development environment, this change should have no impact

Replacing `minimum_keyspace_rf` config option with 4 config options:
`{minimum,maximum}_replication_factor_{warn,fail}_threshold`, which
allow us to impose soft limits (issue a warning) and hard limits (not
execute CQL) on RF when creating/altering a keyspace.
The reason to rather replace than extend `minimum_keyspace_rf` config
option is to be aligned with Cassandra, which did the same, and has the
same parameters' names.
Only min soft limit is enabled by default and it is set to 3, which means
that we'll generate a CQL warning whenever RF is set to either 1 or 2.
RF's value of 0 is always allowed and means that there will not be any
replicas on a given DC. This was agreed with PM.
Because we don't allow to change guardrails' values when scylla is
running (per PM), there're no tests provided with this PR, and dtests will be
provided separately.
Exceeding guardrails' thresholds will be tracked by metrics.

Index caching was disabled by default because it caused performance regressions
for some small-partition workloads. See https://github.com/scylladb/scylladb/issues/11202.
However, it also means that there are workloads which could benefit from the
index cache, but (by default) don't.
As a compromise, we can set a default limit on the memory usage of index cache,
which should be small enough to avoid catastrophic regressions in
small-partition workloads, but big enough to accommodate workloads where
index cache is obviously beneficial.
This series adds such a configurable limit, sets it to to 0.2 of total cache memory by default,
and re-enables index caching by default.

This series ensures that endpoint state changes (for each single endpoint) are applied to the gossiper endpoint_state_map as a whole and on all shards.
Any failure in the process will keep the existing endpoint state intact.
Note that verbs that modify the endpoint states of multiple endpoints may still succeed to modify some of them before hitting an error and those changes are committed to the endpoint_state_map, so we don't ensure atomicity when updating multiple endpoints' states.

When sending mutation to remote endpoint,
the selected endpoints must be in sync with
the current effective_replication_map.
Currently, the endpoints are sent down the storage_proxy
stack, and later on an effective_replication_map is retrieved
again, and it might not match the target or pending endpoints,
similar to the case seen in https://github.com/scylladb/scylladb/issues/15138
The correct way is to carry the same effective replication map
used to select said endpoints and pass it down the stack.

Currently he gossiper marks endpoint_state objects as alive/dead.
I some cases the endpoint_state::is_alive function is checked but in many other cases
gossiper::is_alive(endpoint) is used to determine if the endpoint is alive.
This series removed the endpoint_state::is_alive state and moves all the logic to gossiper::is_alive
that bases its decision on the endpoint having an endpoint_state and being in the _live_endpoints set.
For that, the _live_endpoints is made sure to be replicated to all shards when changed
and the endpoint_state changes are serialized under lock_endpoint, and also making sure that the
endpoint_state in the _endpoint_states_map is never updated in place, but rather a temporary copy is changed
and then safely replicated using gossiper::replicate

We make every alternative type in the request_param variant

We add support for `--ignore-dead-nodes` in `raft_removenode` and
`--ignore-dead-nodes-for-replace` in `raft_replace`. For now, we allow
passing only host ids of the ignored nodes. Supporting IPs is currently
impossible because `raft_address_map` doesn't provide a mapping from IP
to a host id.
The main steps of the implementation are as follows:
- add the `ignore_nodes` column to `system.topology`,
- set the `ignore_nodes` value of the topology mutation in `raft_removenode` and `raft_replace`,
- extend `service::request_param` with alternative types that allow storing a set of ids of the ignored nodes,
- load `ignore_nodes` from `system.topology` into `request_param` in `system_keyspace::load_topology_state`,
- add `ignore_nodes` to `exclude_nodes` in `topology_coordinator::exec_global_command`,
- pass `ignore_nodes` to `replace_with_repair` and `remove_with_repair` in `storage_service::raft_topology_cmd_handler`.
Additionally, we add `test_raft_ignore_nodes.py` with two tests that verify the added changes.

In this PR a simple test for fencing is added. It exercises the data
plane, meaning if it somehow happens that the node has a stale topology
version, then requests from this node will get an error 'stale
topology'. The test just decrements the node version manually through
CQL, so it's quite artificial. To test a more real-world scenario we
need to allow the topology change fiber to sometimes skip unavailable
nodes. Now the algorithm fails and retries indefinitely in this case.
The PR also adds some logs, and removes one seemingly redundant topology
version increment, see the commit messages for details.

We add two new alternative types to service::request_param:
removenode_param and replace_param. They allow storing the list
of ignored nodes loaded from the ignore_nodes column of
system.topology. We also remove the raft::server_id type because
it has been only used by the replace operation.
The problem was that the holder in with_gate
call was released too early. This happened
before the possible call to on_hint_send_failure
in then_wrapped. As a result, the effects of
on_hint_send_failure (segment_replay_failed flag)
were not visible in send_one_file after
ctx_ptr->file_send_gate.close(), so we could decide
that the segment was sent in full and delete
it even if sending of some hints led to errors.
Fixes#15110
There was no indication of problems
in the hints manager metrics before.
We need this counter for fencing tests
in the later commit, but it seems to be
useful on its own.
Three places handle comma-separated lists similarly:
- ss::remove_node.set(...) in api::set_storage_service,
- storage_service::parse_node_list,
- storage_service::is_repair_based_node_ops_enabled.
In the next commit, the fourth place that needs the same logic
appears -- storage_service::raft_replace. It needs to load
and parse the --ignore-dead-nodes-for-replace param from config.
Moreover, the code in is_repair_based_node_ops_enabled is
different and doesn't seem right. We swap '\"' and '\'' with ' '
but don't do anything with it afterward.
To avoid code duplication and fix is_repair_based_node_ops_enabled,
we introduce the new function utils::split_comma_separated_list.
This change has a small side effect on logging. For example,
ignore_nodes_strs in storage_service::parse_node_list might be
printed in a slightly different form.
In the following commits, we add support for --ignore-dead-nodes
in raft_removenode and --ignore-dead-nodes-for-replace in
raft_replace. To make these request parameters accessible for the
topology coordinator, we store them in the new ignore_nodes
column of system.topology.

system_keyspace: fix assertion for missing transition_state
On boot several manipulations with system.local are performed.
1. The host_id value is selected from it with key = local
If not found, system_keyspace generates a new host_id, inserts the
new value into the table and returns back
2. The cluster_name is selected from it with key = local
Then it's system_keyspace that either checks that the name matches
the one from db::config, or inserts the db::config value into the
table
3. The row with key = local is updated with various info like versions,
listen, rpc and bcast addresses, dc, rack, etc. Unconditionally
All three steps are scattered over main, p.1 is called directly, p.2 and
p.3 are executed via system_keyspace::setup() that happens rather late.
Also there's some touch of this table from the cql_test_env startup code.
The proposal is to collect this setup into one place and execute it
early -- as soon as the system.local table is populated. This frees the
system_keyspace code from the logic of selecting host id and cluster
name leaving it to main and keeps it with only select/insert work.

If `live_updatable_config_params_changeable_via_cql` is set to true, configuration parameters defined with `liveness::LiveUpdate` option can be updated in the runtime with CQL, i.e. by updating `system.config` virtual table.
If we don't want any configuration parameter to be changed in the

set to false. This option should be set to false for e.g. cloud users,
who can only perform CQL queries, and should not be able to change

returned to the user can be not fully accurate, consider:

```
where `task_ttl_in_seconds` has been defined with
`liveness::LiveUpdate`, but because `live_updatable_config_params_changeable_via_cql` is set to
`false` in `scylla.yaml,` `task_ttl_in_seconds` cannot be modified in the
