We introduce a new term in the glossary: RF-rack-valid keyspace. We also highlight in our user documentation that all keyspaces must remain RF-rack-valid throughout their lifetime, and failing to guarantee that may result in data inconsistencies or other issues. We base that information on our experience with materialized views in keyspaces using tablets, even though they remain an experimental feature. Along with the new term, we introduce a new configuration option called `rf_rack_valid_keyspaces`, which, when enabled, will enforce preserving all keyspaces RF-rack-valid. That functionality will be implemented in upcoming commits. For now, we materialize the restriction in form of a named requirement: a function verifying that the passed keyspace is RF-rack-valid. The option is disabled by default. That will change once we adjust the existing tests to the new semantics. Once that is done, the option will first be enabled by default, and then it will be removed. Fixes scylladb/scylladb#20356
