The tag was lately renamed from `experimental:initial_tablets` to
`system::initial_tablets`. This commit fixes both the tests as well as
the exceptions sent to the user instructing how to create table with
vnodes.
The test test_mv_tablets_replace verifies that merging tablets of both a
view and its base table is allowed if rf-rack-valid-keyspaces option is
enabled (and it is enabled by default in the test suite).
introduce tiering marks
1 “unstable” - For unstable tests that will be will continue runing every night and generate up-to-date statistics with failures without failing the “Main” verification path(scylla-ci, Next)
2 “nightly” - for tests that are quite old, stable, and test functionality that rather not be changed or affected by other features, are partially covered in other tests, verify non-critical functionality, have not found any issues or regressions, too long to run on every PR, and can be popped out from the CI run.
set 7 long tests(according to statistic in elastic) as nightly(theses 8 tests took 20% of CI run,
about 4 hours without paralelization)
1 test as unstable(as exaple ot marker usage)

This commits introduces an config option 'tablet_load_stats_refresh_interval_in_seconds'
that allows overriding the default value without using error injection.

Replace the duplicated get_tablet_replicas method in test_mv_tablets
with the common method from the tablets api, to reduce code duplication
and use the correct method that reads the tablet replicas from the base
table.
In test_tablet_mv_replica_pairing_during_replace, after we create
the tables, we want to wait for their tablets to distribute evenly
across nodes and we have a wait_for for that.
But we don't await this wait_for, so it's a no-op. This patch fixes
it by adding the missing await.

In the test test_tablet_mv_replica_pairing_during_replace we stop 2 out of 4 servers while using RF=2.
Even though in the test we use exactly 4 tablets (1 for each replica of a base table and view), intially,
the tablets may not be split evenly between all nodes. Because of this, even when we chose a server that
hosts the view and a different server that hosts the base table, we sometimes stoped all replicas of the
base or the view table because the node with the base table replica may also be a view replica.
After some time, the tablets should be distributed across all nodes. When that happens, there will be
no common nodes with a base and view replica, so the test scenario will continue as planned.
In this patch, we add this waiting period after creating the base and view, and continue the test only
when all 4 tablets are on distinct nodes.

This test shuts down a node and then replaces it with another one while
continuously writing to the cluster. The test has been observed to take
a lot of time in debug mode and time out on the replace operation.
Replace takes very long because rebuilding tablets on the new node is
very slow, and the slowest part is memtable flush which happens at the
beginning of streaming. The slowness seems to be specific to the debug
mode.
Turn off the test in debug mode to deflake the CI. As a follow-up, the
test is planned to be reworked into an quicker error injection test so
that the code path tested by this test will be again exercised in debug
unit tests (scylladb/scylladb#23898)

This series add a new config option: `tablets_mode_for_new_keyspaces` that replaces the existing
`enable_tablets` option. It can be set to the following values:
disabled: New keyspaces use vnodes by default, unless enabled by the tablets={'enabled':true} option
enabled: New keyspaces use tablets by default, unless disabled by the tablets={'disabled':true} option
enforced: New keyspaces must use tablets. Tablets cannot be disabled using the CREATE KEYSPACE option
`tablets_mode_for_new_keyspaces=disabled` or `tablets_mode_for_new_keyspaces=enabled` control whether
tablets are disabled or enabled by default for new keyspaces, respectively.
In either cases, tablets can be opted-in or out using the `tablets={'enabled':...}`
keyspace option, when the keyspace is created.
`tablets_mode_for_new_keyspaces=enforced` enables tablets by default for new keyspaces,
like `tablets_mode_for_new_keyspaces=enabled`.
However, it does not allow to opt-out when creating
new keyspaces by setting `tablets = {'enabled': false}`

The new option deprecates the existing `enable_tablets` option.
It will be extended in the next patch with a 3rd value: "enforced"
while will enable tablets by default for new keyspace but
without the posibility to opt out using the `tablets = {'enabled':
false}` keyspace schema option.

This fixes an issue where materialized view tablets are not split
because they are not registered as split candidates by the storage
service.
The code in storage_service::replicate_to_all_cores was changed in
4bfa3060d0 to handle normal tables and view tables separately, but with
that change register_tablet_split_candidate is applied only to normal
tables and not every table like before. We fix it by registering view
tables as well.
We add a test to verify that split of MV tables works.
