Remove V2 get_catalog from catalog driver

The get_catalog method on the catalog driver interface and its SQL
implementation format the service catalog in the legacy V2 layout.
Since the V2 API was removed, no code path calls this method. The
entire codebase uses get_v3_catalog exclusively.

Remove the abstract definition and the ~65-line SQL implementation
to reduce dead code.
