gbproxy: Add 'patch-ptmsi' command to enable TLLI/P-TMSI patching
This VTY command add the following commands to the gbproxy node:
- patch-ptmsi: Enables P-TMSI/TLLI patching
- no patch-ptmsi: Disables P-TMSI/TLLI patching
Note that using these commands interactively can load to undefined
behavior of existing LLC connections.
