cql3/select_statement: do not parallelize single-partition aggregations
This check is already in place, but isn't fully working, i.e.
switching from a vnode KS to a tablets KS is not allowed, but
this check doesn't work in the other direction. To fix the
latter, `ks_prop_defs::get_initial_tablets()` has been changed
to handle 3 states: (1) init_tablets is set, (2) it was skipped,
(3) tablets are disabled. These couldn't fit into std::optional,
so a new local struct to hold these states has been introduced.
Callers of this function have been adjusted to set init_tablets
to an appropriate value according to the circumstances, i.e. if
tablets are globally enabled, but have been skipped in the CQL,
init_tablets is automatically set to 0, but if someone executes
ALTER KS and doesn't provide tablets options, they're inherited
from the old KS.
I tried various approaches and this one resulted in the least
lines of code changed. I also provided testcases to explain how
the code behaves.

Said method has a func parameter (called just f), which it receives as
rvalue ref and just uses as a reference. This means that if caller
doesn't keep the func alive, for_each_cql_result() will run into
use-after-free after the first suspention point. This is unexpected for
callers, who don't expect to have to keep something alive, which they
passed in with std::move().
Adjust the signature to take a value instead, value parameters are moved
to the coro frame and survive suspention points.
Adjust internal callers (query_internal()) the same way.
There are no known vulnerable external callers.

[avi: adjust test/alternator/suite.yaml to reflect new keyspace]
Up until now we waited until mutations are in place and then returned
directly to the caller of the ALTER statement, but that doesn't imply
that tablets were deleted/created, so we must wait until the whole
processing is done and return only then.
We want to ensure that when the replication factor
of a keyspace changes, it changes by at most 1 per DC
if it uses tablets. The rationale for that is to make
sure that the old and new quorums overlap by at least
one node.
After these changes, attempts to change the RF of
a keyspace in any DC by more than 1 will fail.
This patch removes the support for the "wildcard" replication_factor
option for ALTER KEYSPACE when the keyspace supports tablets.
It will still be supported for CREATE KEYSPACE so that a user doesn't
have to know all datacenter names when creating the keyspace,
but ALTER KEYSPACE will require that and the user will have to
specify the exact change in replication factors they wish to make by
explicitly specifying the datacenter names.
Expanding the replication_factor option in the ALTER case is
unintuitive and it's a trap many users fell into.
See #8881, #15391, #16115
This commit adds support for executing ALTER KS for keyspaces with
tablets and utilizes all the previous commits.
The ALTER KS is handled in alter_keyspace_statement, where a global
topology request in generated with data attached to system.topology
table. Then, once topology state machine is ready, it starts to handle
this global topology event, which results in producing mutations
required to change the schema of the keyspace, delete the
system.topology's global req, produce tablets mutations and additional
mutations for a table tracking the lifetime of the whole req. Tracking
the lifetime is necessary to not return the control to the user too
early, so the query processor only returns the response while the
mutations are sent.
With current implementation only 1 global topo req can be executed at a
time, so when ALTER KS is executed, we'll have to check if any other
global topo req is ongoing and fail the req if that's the case.
If the user wants to change the default initial tablets value, it uses ALTER KEYSPACE statement. However, specifying `WITH tablets = { initial: $value }` will take no effect, because statement analyzer only applies `tablets` parameters together with the `replication` ones, so the working statement should be `WITH replication = $old_parameters AND tablets = ...` which is not very convenient.
This PR changes the analyzer so that altering `tablets` happens independently from `replication`. Test included.

The function intersection(r1,r2) in statement_restrictions.cc is used
when several WHERE restrictions were applied to the same column.
For example, for "WHERE b<1 AND b<2" the intersection of the two ranges
is calculated to be b<1.
As noted in issue #18690, Scylla is inconsistent in where it allows or
doesn't allow these intersecting restrictions. But where they are
allowed they must be implemented correctly. And it turns out the
function intersection() had a bug that caused it to sometimes enter
an infinite loop - when the intent was only to call itself once with
swapped parameters.
This patch includes a test reproducing this bug, and a fix for the
bug. The test hangs before the fix, and passes after the fix.
While at it, I carefully reviewed the entire code used to implement
the intersection() function to try to make sure that the bug we found
was the only one. I also added a few more comments where I thought they
were needed to understand complicated logic of the code.

Instead, use shard_for_reads(). The justification is that:
1) In cas_shard(), we need to pick a single request coordinator.
shard_for_reads() gives that, which is equivalent to shard_of()
if there is no intra-node migration.
2) In paxos handler for prepare(), the shard we execute it on is
the shard from which we read, so shard_for_reads() is the one.
3) Updates of paxos state are separate CQL requests, and use their
own sharding.
4) Handler for learn is executing updates using calls to
storage_proxy::mutate_locally() which will use the right sharder for writes
However, the code is still not prepared for intra-node migration, and
possibly regular migration too in case of abandoned requests, because
the locking of paxos state assumes that the shard is static. That
would have to be fixed separately, e.g. by locking both shards
(shard_for_writes()) during migration, so that the set of locked
shards always intersects during migration and local serialization of
paxos state updates is achieved. I left FIXMEs for that.

Currently all tables are printed in statements like `DESC TABLES`, `DESC KEYSPACE ks` or `DESC SCHEMA`.
But when we create a table with cdc enabled, additional table with `_scylla_cdc_log` suffix is created.
Those tables shouldn't be recreated manually but created automatically when the base table is created.
This patch hides tables with `_scylla_cdc_log` suffix in all describe statements.

More than three years ago, in issue #7949, we noticed that trying to
set a `map<ascii, int>` from JSON input (i.e., using INSERT JSON or the
fromJson() function) fails - the ascii key is incorrectly parsed.
We fixed that issue in commit 75109e9519
but unfortunately, did not do our due diligence: We did not write enough
tests inspired by this bug, and failed to discover that actually we have
the same bug for many other key types, not just for "ascii". Specifically,
the following key types have exactly the same bug:
* blob
* date
* inet
* time
* timestamp
* timeuuid
* uuid
Other types, like numbers or boolean worked "by accident" - instead of
parsing them as a normal string, we asked the JSON parser to parse them
again after removing the quotes, and because unquoted numbers and
unquoted true/false happwn to work in JSON, this didn't fail.
The fix here is very simple - for all *native* types (i.e., not
collections or tuples), the encoding of the key in JSON is simply a
quoted string - and removing the quotes is all we need to do and there's
no need to run the JSON parser a second time. Only for more elaborate
types - collections and tuples - we need to run the JSON parser a
second time on the key string to build the more elaborate object.
This patch also includes tests for fromJson() reading a map with all
native key types, confirming that all the aforementioned key types
were broken before this patch, and all key types (including the numbers
and booleans which worked even befoe this patch) work with this patch.

When a table has secondary indexes on *multiple* columns, and several
such columns are used for filtering in a query, Scylla chooses one
of these indexes as the main driver of the query, and the second
column's restriction is implemented as filtering.
Before this patch, the index to use was chosen fairly randomly, based on
the order of the indexes in the schema. This order may be different in
different coordinators, and may even change across restarts on the same
coordinators. This is not only inconsistent, it can cause outright wrong
results when using *paging* and switching (or restarting) coordinates
in the middle of a paged scan... One coordinator saves one index's key
in the paging state, and then the other coordinator gets this paging
state and wrongly believes it is supposed to be a key of a *different*
index.
The fix in this patch is to pick the index suitable for the first
indexed column mentioned in the query. This has two benefits over
the situation before the patch:
1. The decision of which index to use no longer changes between
coordinators or across restarts - it just depends on the schema
and the specific query.
2. Different indexes can have different "specificity" so using one
or the other can change the query's performance. After this patch,
the user is in control over which index is used by changing the
order of terms in the query. A curious user can use tracing to
check which index was used to implement a particular query.
An xfailing test we had for this issue no longer fails, so the "xfail"
marker is removed.

- insert some data1
- drop column b
- add column b int
- insert some data2
If the sstables weren't compacted, after restoring the schema from description:
- we will loss column b in data2 if we simply do `ALTER TABLE t DROP b` and `ALTER TABLE t ADD b int`
- we will resurrect column b in data1 if we skip dropping and re-adding the column

is signed char, not char. this issue does not exist in {fmt} v10,
so, in this change, we add a workaround to explicitly specialize
the type trait to assure that {fmt} format this type using its
`fmt::formatter` specialization instead of trying to format it
as a string. also, {fmt}'s generic ranges formatter calls the
pair formatter's `set_brackets()` and `set_separator()` methods
when printing the range, but operator<< based formatter does not
provide these method, we have to include this change in the change
switching to {fmt}, otherwise the change specializing
`fmt::details::is_std_string_like<bytes>` won't compile.
* test/boost: in tests, we use `BOOST_REQUIRE_EQUAL()` and its friends
for comparing values. but without the operator<< based formatters,
Boost.Test would not be able to print them. after removing
the homebrew formatters, we need to use the generic

because the inherited `format()` method actually comes from

`string_view` is actually `fmt::string_view`. this follows
the document at

and since there is less indirection under the hood -- we do not
use the specialization created by `FMT_FORMAT_AS` which inherit
from `formatter<fmt::string_view>`, hopefully this can improve
the compilation speed a little bit. also, this change addresses
the build failure with {fmt} v10.

Before the patch selection of auth version depended

is not supported.
During recovery auth works in read-only mode, writes
will fail.
