gbproxy: Extend the match-imsi VTY command to support categories

Browse Source 
This patch modifies the match-imsi command to allow for different
match categories (currently only 'patching' is provided).

  - match-imsi patching RE : Filter APN patching and routing
  - no match-imsi          : Clear all filter expressions
