Added a new POST endpoint `/storage_service/drop_quarantined_sstables` to the REST API.
This endpoint allows dropping all quarantined SSTables either globally or
for a specific keyspace and tables.
Optional query parameters `keyspace` and `tables` (comma-separated table names) can be
provided to limit the scope of the operation.

The topology coordinator executes several topology cmd rpc against some nodes
during a topology change. A topology operation will not proceed unless
rpc completes (successfully or not), but sometimes it appears that it
hangs and it is hard to tell on which nodes it did not complete yet.
Introduce new REST endpoint that can help with debugging such cases.
If executed on the topology coordinator it returns currently running
topology rpc (if any) and a list of nodes that did not reply yet.
This patch adds the new option in nodetool, patches the
load_new_ss_tables REST request with a new parameter and
skips the reshape step in refresh if this flag is passed.

This change adds the --scope option to nodetool refresh.
Like in the case of nodetool restore, you can pass either of:
* node - On the local node.
* rack - On the local rack.
* dc - In the datacenter (DC) where the local node lives.
* all (default) - Everywhere across the cluster.

The feature is based on the existing load_and_stream paths, so it
requires passing --load-and-stream to the refresh command.
Also, it is not compatible with the --primary-replica-only option.

Currently, the `system.compaction_history` table miss information like the type of compaction (cleanup, major, resharding, etc), the sstable generations involved (in and out), shard's id the compaction was triggered on and statistics on purged tombstones to be collected during compaction.
The series extends the table with the following columns:
- "compaction_type" (text)
- "shard_id" (int)
- "sstables_in" (list<sstableinfo_type>)
- "sstables_out" (list<sstableinfo_type>)
- "total_tombstone_purge_attempt" (long)
- "total_tombstone_purge_failure_due_to_overlapping_with_memtable" (long)
- "total_tombstone_purge_failure_due_to_overlapping_with_uncompacting_sstable" (long)
with a user defined type `sstableinfo_type` that holds the information about sstable file
- generation (uuid)
- origin (text)
- size (long)
Additional statistics stored in the compaction_history have been incorporated in the API `/compaction_manager/compaction_history` and the `nodetool compactionhistory` command.
No backport is required. It extends the existing compaction history output.

Add an API call which estimates the effectiveness of possible
compression config changes.
This can be used to make an informed decision about whether to
change the compression method, without actually recompressing
any SSTables.
Add an API call which will retrain the SSTable compression dictionary

Currently, it needs all nodes to be alive to succeed. We can relax this later.
Currently, the tablet repair scheduler repairs all replicas of a tablet.
It does not support hosts or DCs selection. It should be enough for most
cases. However, users might still want to limit the repair to certain
hosts or DCs in production. #21985 added the preparation work to add the
config options for the selection. This patch adds the hosts or DCs
selection support.

Set true to wait for the repair to complete. Set false to skip waiting
for the repair to complete. When the option is not provided, it defaults
to false.
It is useful for management tool that wants the api to be async.

Previously, during backup, SSTable components are preserved in the
snapshot directory even after being uploaded. This leads to redundant
uploads in case of failed backups or restarts, wasting time and
resources (S3 API calls).
This change
- adds an optional query parameter named "move_files" to
"/storage_service/backup" API. if it is set to "true", SSTable
components are removed once they are backed up to object storage.
- conditionally removes SSTable components from the snapshot directory once
they are successfully uploaded to the target location. This prevents
re-uploading the same files and reduces disk usage.
This change only "Refs" #20655, because, we can move further optimize
the backup process, consider:
- Sending HEAD requests to S3 to check for existing files before uploading.
- Implementing support for resuming partially uploaded files.

Introduces two endpoints with operations specific to service levels:
- switch_tenants: updates the scheduling group of all connections to be
aligned with the service level specific to the logged in user. This is
mostly legacy API, as with service levels on raft this is done
automatically.
- count_connections: for each user and for each scheduling group, counts
how many connections are assigned to that user and scheduling group.
This API is used in tests.
There are two of those -- the POST /storage_service/keyspace that loads
and streams new sstables from /upload and POST /storage_service/restore
that does the same, but gets sstables from object store.
The new optional parameter allow users to tun the streaming phase
behavior. The test/pylib client part is also updated here.

Added a new parameter `consider_only_existing_data` to major compaction
API endpoints. When enabled, major compaction will:
- Force-flush all tables.
- Force a new active segment in the commit log.
- Compact all existing SSTables and garbage-collect tombstones by only
checking the SSTables being compacted. Memtables, commit logs, and
other SSTables not part of the compaction will not be checked, as they
will only contain newer data that arrived after the compaction
started.
The `consider_only_existing_data` is passed down to the compaction
descriptor's `gc_check_only_compacting_sstables` option to ensure that
only the existing data is considered for garbage collection.
The option is also passed to the `maybe_flush_commitlog` method to make
sure all the tables are flushed and a new active segment is created in
the commit log.

The method starts a task that uploads all files from the given
keyspace's snapshot to the requested endpoint/bucket. The task runs in
the background, its task_id is returned from the method once it's
spawned and it should be used via /task_manager API to track the task
execution and completion (hint: it's good to have non-zero TTL value to
make sure fast backups don't finish before the caller manages to call
wait_task API).
If snapshot doesn't exist, nothing happens (FIXME, need to return back
an error in that case).
If endpoint is not configured locally, the API call resolves with
bad-request instantly.
Sstables components are scanned for all tables in the keyspace and are
uploaded into the /bucket/${cf_name}/${snapshot_name}/ path.
Task is not abortable (FIXME -- to be added) and doesn't really report
its progress other than running/done state (FIXME -- to be added too).

Add a CQL server testing API with and endpoint to dump
service level parameters of all CQL connections.
This endpoint will be later used to test functionality of
automated updating CQL connections parameters.
Virtual tasks are supported by get_task_status, abort_task and
wait_task.
Task status returned by get_task_status and wait_task:
- contains task_kind to indicate whether it's virtual (cluster) or
regular (node) task;
- children list apart from task_id contains node address of the task.
task_manager/list_module_tasks/{module} starts supporting virtual tasks,
which means that their stats will also be shown for users.
Additional task_kind param is added to indicate whether the task is
virutal (cluster-wide) or regular (node-wide).
Support in other paths will be added in following patches.
Current upgrade dtest rely on a ccm node function to
get_highest_supported_sstable_version() that looks for
r'Feature (.*)_SSTABLE_FORMAT is enabled' in the log files.
Starting from scylla-6.0 ME_SSTABLE_FORMAT is enabled by default
and there is no cluster feature for it. Thus get_highest_supported_sstable_version()
returns an empty list resulting in the upgrade tests failures.
This change introduces a seperate API path that returns the highest
supported sstable format (one of la, mc, md, me) by a scylla node.

This will allow to trigger the read barrier directly via the API,
instead of doing work-arounds (like dropping a non-existent table).
The intended use-case is in the Scylla Manager, to make sure that
the database schema is up to date after the data has been backed up
and before attempting to backup the database schema.
The database schema in particular is being backed up just on a single
node, which might not yet have the schema at least as new as the data
(data can be migrated to a newer schema, but not a vice-versa).
The read barrier issued on the node should ensure that the node should
have the schema at least as new as the data or newer.
