Fixes #22688 If we set a dc rf to zero, the options map will still retain a dc=0 entry. If this dc is decommissioned, any further alters of keyspace will fail, because the union of new/old options will now contained an unknown keyword. Change alter ks options processing to simply remove any dc with rf=0 on alter, and treat this as an implicit dc=0 in nw-topo strategy. This means we change the reallocate_tablets routine to not rely on the strategy objects dc mapping, but the full replica topology info for dc:s to consider for reallocation. Since we verify the input on attribute processing, the amount of rf/tablets moved should still be legal. v2: * Update docs as well. v3: * Simplify dc processing * Reintroduce options empty check, but do early in ks_prop_defs * Clean up unit test some Closes scylladb/scylladb#22693

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.
