> currently , we allow upgrade of system tables to map to system namespace by enabling "phoenix.schema.mapSystemTablesToNamespace" config (conjuction with "phoenix.connection.isNamespaceMappingEnabled")
> but we need to ensure following things whenever client connects with above config:-
> 1. Server should be upgraded and check consistency of these properties between client and server.
> 2. If above property does not exists but system:catalog exists, we should not start creating system.catalog.
> 3. if old client connects, it should not create system.catalog again ignoring the upgrade and start using it.
