gbproxy: Use a separate regexp for routing
Currently one regexp ('patching') is used for all matching.
This patch adds a second category 'routing' which is exclusively used
for SGSN selection. It also adds a corresponding VTY command:
- match-imsi patching RE : MS related patching (currently APN)
- match-imsi routing RE : Select secondary SGSN on match only
- no match-imsi : Clear all filter expressions
Ticket: OW#1258
