Alternator is a coordinator-side service and so should not access the replica module. In this series all but one of uses of the replica module are replaced with data_dictionary. One case remains - accessing the replication map which is not available (and should not be available) via the data dictionary. The data_dictionary module is expanded with missing accessors. Closes #9945 * github.com:scylladb/scylla: alternator: switch to data_dictionary for table listing purposes data_dictionary: add get_tables() data_dictionary: introduce keyspace::is_internal()
