System Connector

The System Connector now works like other connectors: global systemtables are only available in the system catalog, rather than in a specialschema that is available in every catalog. Additionally, connectors may nowprovide system tables that are available within that connector’s catalog byimplementing the getSystemTables() method on the Connector interface.
