This series extends the table schema with per-table tablet options. The options are used as hints for initial tablet allocation on table creation and later for resize (split or merge) decisions, when the table size changes. * New feature, no backport required Closes scylladb/scylladb#22090 * github.com:scylladb/scylladb: tablets: resize_decision: get rid of initial_decision tablet_allocator: consider tablet options for resize decision tablet_allocator: load_balancer: table_size_desc: keep target_tablet_size as member network_topology_strategy: allocate_tablets_for_new_table: consider tablet options network_topology_strategy: calculate_initial_tablets_from_topology: precalculate shards per dc using for_each_token_owner network_topology_strategy: calculate_initial_tablets_from_topology: set default rf to 0 cql3: data_dictionary: format keyspace_metadata: print "enabled":true when initial_tablets=0 cql3/create_keyspace_statement: add deprecation warning for initial tablets test: cqlpy: test_tablets: add tests for per-table tablet options schema: add per-table tablet options feature_service: add TABLET_OPTIONS cluster schema feature

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
