This option was silently broken when --enable-tablet's default changed
from false to true. The reason is that when --vnodes is passed, run only
removes --enable-tablets=true from scylla's command line. With the new
default this is not enough, we need to explicitely disable tablets to
override the default.

Increase pool size changes were recently reverted because of the flakiness for the test_gossip_boot test. Test started
to fail on adding the node to the cluster without any issues in the Scylla log file. In test logs it looked like the
installation process for the new node just hanged. After investigating the problem, I've found out that the issue is that
test.py was draining the io_executor pool for cleaning the directory during install that was set to eight workers. So
to fix the issue, io_executor pool should be increased to more or less the same ratio as it was: doubled cluster pool size.

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.
After c1b2b8cb2c /task_manager/wait_task/
does not unregister tasks anymore.
Delete the check if the task was unregistered from test_task_manager_wait.
Check task status in drain_module_tasks to ensure that the task
is removed from task manager.

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.

In CI test always executed with option --repeat=3 that leads to generate 3 test results with the same name. Junit plugin in CI cannot distinguish correctly the difference between these results. In case when we have two passes and one fail, the link to test result will sometimes be redirected to the incorrect one because the test name is the same.
To fix this ReportPlugin added that will be responsible to modify the test case name during junit report generation adding to the test name mode and run id.

Task manager's tasks stay in memory after they are finished.
Moreover, even if a child task is unregistered from task manager,
it is still alive since its parent keeps a foreign pointer to it. Also,
when a task has finished successfully there is no point in keeping
all of its descendants in memory.
The patch introduces folding of task manager's tasks. Whenever
a task which has a parent is finished it is unregistered from task
manager and foreign_ptr to it (kept in its parent) is replaced
with its status. Children's statuses of the task are dropped unless
they or one of their descendants failed. So for each operation we
keep a tree of tasks which contains:
- a root task and its direct children (status if they are finished, a task
otherwise);
- running tasks and their direct children (same as above);
- a statuses path from root to failed tasks.
/task_manager/wait_task/ does not unregister tasks anymore.

We make the `consistent-topology-changes` experimental feature
unused and assumed to be true in 6.0. We remove code branches that
executed if `consistent-topology-changes` was disabled.
`database::find_column_family()` throws no_such_column_family
if an unknown ks.cf is fed to it. and we call into this function
without checking for the existence of ks.cf first. since
"/storage_service/tablets/move" is a public interface, we should
translate this error to a better http error.
in this change, we check for the existence of the given ks.cf, and
throw an exception so that it can be caught by seastar::httpd::routers,
and converted to an HTTP error.

Since 6b87778 regular compaction tasks are removed from task manager
immediately after they are finished.
test_regular_compaction_task lists compaction tasks and then requests
their statuses. Only one regular compaction task is guaranteed to still
be running at that time, the rest of them may finish before their status
is requested and so it will no longer be in task manager, causing the test
to fail.
Fix statuses check to consider the possibility of a regular compaction
task being removed from task manager.

This change introduces a logic, that is responsible
for checking if tablets are enabled for any of
keyspaces when get_ownership() is invoked.
Without it, the result would be calculated
based solely on sorted_tokens() which was

Before this change, when user tried to utilize
'storage_service/ownership/{keyspace}' API with
keyspace parameter that uses tablets, then internal
error was thrown. The code was calling a function,
that is intended for vnodes: get_vnode_effective_replication_map().
This commit introduces graceful handling of such scenario and
extends the API to allow passing 'cf' parameter that denotes
table name.
Now, when keyspace uses tablets and cf parameter is not passed
a descriptive error message is returned via BAD_REQUEST.
Users cannot query ownership for keyspace that uses tablets,
but they can query ownership for a table in a given keyspace that uses tablets.
Also, new tests have been added to test/rest_api/test_storage_service.py and
to test/topology_experimental_raft/test_tablets.py in order to verify the behavior
with and without tablets enabled.

This change is intended to introduce tests for vnodes for
the following API paths:
- 'storage_service/ownership'
- 'storage_service/ownership/{keyspace}'
In next patches the logic that is tested will be adjusted
to work correctly when tablets are enabled. This is a safety
net that ensures that the logic is not broken.

Fix test_storage_service.py to work with tablets.
- test_describe_ring was failing because in storage_service/describe_ring
table must be specified for keyspaces with tablets.
Do not check the status if tablets are enabled. Add checks for
specified table;
- test_storage_service_keyspace_cleanup_with_no_owned_ranges
was failing because cleanup is disabled on keyspaces with tablets.
Use test_keyspace_vnodes fixture to use keyspace with tablet disabled;
- test_storage_service_get_natural_endpoints required
some minor type-related fixes.
Fix test_compaction_task.py to work with tablets.
Currently test fail because cleanup on keyspace with tablets is
disabled, and reshape and reshard of keyspace with tablets uses
load_and_stream which isn't covered by tasks.
Use test_keyspace_vnodes for these tests to have a keyspace with
tablets disabled.
To allow to filter the returned keyspaces based by the replication they
use: tablets or vnodes.
The filter can be disabled by omitting the parameter or passing "all".
The default is "all".

This API endpoint was failing when tablets were enabled
because of usage of get_vnode_effective_replication_map().
Moreover, it was providing an error message that was not
user-friendly.
This change extends the handler to properly service the incoming requests.
Furthermore, it introduces two new test cases that verify the behavior of
storage_service/range_to_endpoint_map API. It also adjusts the test case
of this endpoint for vnodes to succeed when tablets are enabled by default.
The new logic is as follows:
- when tablets are disabled then users may query endpoints
for a keyspace or for a given table in a keyspace
- when tablets are enabled then users have to provide
table name, because effective replication map is per-table
When user does not provide table name when tablets are enabled
for a given keyspace, then BAD_REQUEST is returned with a
meaningful error message.

per its description, "`/storage_service/describe_ring/`" returns the
token ranges of an arbitrary keyspace. actually, it returns the
first keyspace which is of non-local-vnode-based-strategy. this API
is not used by nodetool, neither is it exercised in dtest.
scylla-manager has a wrapper for this API though, but that wrapper
is not used anywhere.

delete test_running_compaction_task_abort (relying on regular compaction)
which checks are already achived by test_not_created_compaction_task_abort.
Rename the latter.

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.
