purpose Cql statements used to have two API functions, depends_on_keyspace and depends_on_column_family. The former, took as a parameter only a table name, which makes no sense. There could be multiple tables with the same name each in a different keyspace and it doesn't make sense to generalize the test - i.e to ask "Does a statement depend on any table named XXX?" In this change we unify the two calls to one - depends on that takes a keyspace name and optionally also a table name, that way every logical dependency tests that makes sense is supported by a single API call.
