For major compacting all tables in the database.
The advantage of this api is that `commitlog->force_new_active_segment`
happens only once in `database::flush_all_tables` rather than
once per keyspace (when `nodetool compact` translates to
a sequence of `/storage_service/keyspace_compaction` calls).

When flushing is done externally, e.g. by running
`nodetool flush` prior to `nodetool compact`,
flush_memtables=false can be passed to skip flushing
of tables right before they are major-compacted.
This is useful to prevent creation of small sstables
due to excessive memtable flushing.

This reverts commit 11cafd2fc8, reversing
changes made to 2bae14f743.
Reverting because this series causes frequent CI failures, and the
proposed quickfix causes other failures of its own.
Fixes: #16113
This reverts commit 2860d43309, reversing
changes made to a3621dbd3e.
Reverting because rest_api.test_compaction_task started failing after
this was merged.
Fixes: #16005
Compaction tasks which do not have a parent are abortable
through task manager. Their children are aborted recursively.
Compaction tasks of the lowest level are aborted using existing
compaction task executors stopping mechanism.

test_storage_service_keyspace_cleanup_with_no_owned_ranges
from test_storage_service.py creates snapshots with tags based
on current time. Thus if a test runs on the same node twice
with time distance short enough, there may be a name collision
between the snapshots from two runs. This will cause the second
run to fail on assertions.
Use new_test_snapshot fixture to drop snapshots after the test.
Delete my_snapshot_tags as it's no longer necessary.

`sync_point` API provided with incorrect sync point id might allocate
crazy amount of memory and fail with `std::bad_alloc`.
To fix this, we can check if the encoded sync point has been modified
before decoding. We can achieve this by calculating a checksum before
encoding, appending it to the encoded sync point, and compering it with
a checksum calculated in `db::hints::decode` before decoding.

When running compaction task test on the same scylla instantion
other tests are run, some compaction tasks from other test cases may
be left in task manager. If they stay in memory long enough, they may
get unregistered during the compaction task test and cause bad_request
status.
Drain old compaction tasks before and after each test.

This reverts commit 2a58b4a39a, reversing
changes made to dd63169077.
After patch 87c8d63b7a,
table_resharding_compaction_task_impl::run() performs the forbidden
action of copying a lw_shared_ptr (_owned_ranges_ptr) on a remote shard,
which is a data race that can cause a use-after-free, typically manifesting
as allocator corruption.
Note: before the bad patch, this was avoided by copying the _contents_ of the
lw_shared_ptr into a new, local lw_shared_ptr.

Return 400 Bad Request instead of 500 Internal Server Error
when user requests task or module which does not exist through
task manager and task manager test apis.
Closes#14166
* github.com:scylladb/scylladb:
test: add test checking response status when requested module does not exist
api: fix indentation
api: throw bad_param_exception when requested task/module does not exists
In task manager and task manager test rest apis when a task or module
which does not exist is requested, we get Internal Server Error.
In such cases, wrap thrown exceptions in bad_param_exception
to respond with Bad Request code.
Modify test accordingly.
In test_compaction_task.py tests concerning the same type of compaction
are squashed together so that they are run synchronously and there is
no data race when the tests are run in parallel.
It is possible that a node will have no owned token ranges
in some keyspaces based on their replication strategy,
if the strategy is configured to have no replicas in
this node's data center.
In this case we should go ahead with cleanup that will
effectively delete all data.
Note that this is current very inefficient as we need
to filter every partition and drop it as unowned.
It can be optimized by either special casing this case
or, better, use skip forward to the next owned range.
This will skip to end-of-stream since there are no
owned ranges.

The tests user the discriminator "system" as prefix to assume keyspaces are marked
"internal" inside scylla. This is not true in enterprise universe (replicated key
provider). It maybe/probably should, but that train is sailing right now.
Fix by removing one assert (not correct) and use actual API info in the alternator
test.
