Pavel Emelyanov 3ab43eba01 validation: Cleanup validate_keyspace helpers
One of them uses global storage_proxy instance, but since
it is not used -- remove it not to encourage anybody to start
calling one.

Another call uses the db.find_keyspace to check if a keyspace
exists, while there's a nicer db.has_keyspace helper (which
doesn't throw exceptions) so use it.
