This patch series fixes a couple of bugs around validating if RF is not changed by too much when performing ALTER tablets KS. RF cannot change by more than 1 in total, because tablets load balancer cannot handle more work at once. Fixes: #20039 Should be backported to 6.0 & 6.1 (wherever tablets feature is present), as this bug may break the cluster. Closes scylladb/scylladb#20208 * github.com:scylladb/scylladb: cql: sum of abs RFs diffs cannot exceed 1 in ALTER tablets KS cql: join new and old KS options in ALTER tablets KS cql: fix validation of ALTERing RFs in tablets KS cql: harden `alter_keyspace_statement.cc::validate_rf_difference` cql: validate RF change for new DCs in ALTER tablets KS cql: extend test_alter_tablet_keyspace_rf cql: refactor test_tablets::test_alter_tablet_keyspace cql: remove unused helper function from test_tablets

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.
