Support for TTL-based data removal when using tablets. The essence of this commit is a separate code path for finding token ranges owned by the current shard for the cases when tablets are used and not vnodes. At the same time, the vnodes-case is not touched not to cause any regressions. The TTL-caused data removal is normally performed by the primary replica (both when using vnodes and tablets). For the tablets case, the already-existing method tablet_map::get_primary_replica(tablet_id) is used to know if a shard execuring the TTL-related data removal is the primary replica for each tablet. A new method tablet_map::get_secondary_replica(tablet_id) has been added. It is needed by the data invalidation procedure to remove data when the primary replica node is down - the data is then removed by the secondary replica node. The mechanism is the same as in the vnodes case. Since alternator now supports TTL, the test `test_ttl_enable_error_with_tablets` has been removed. Also, tests in the test_ttl.py have been made to run twice, once with vnodes and once with tablets. When run with tablets, the due to lack of support for LWT with tablets (#18068), tests use 'system:write_isolation' of 'unsafe_rmw'. This approach allows early regression testing with tablets and is meant only as a tentative solution. Fixes scylladb/scylladb#16567 Closes scylladb/scylladb#23662
