gprs/vty: Add commands to manage the TLLI list
These commands manage the TLLI list used to decide whether an APN
shall be patched or not. Note that this list is (currently) only
maintained if IMSI matching is used.
VTY commands (enable node):
show gbproxy tllis show all TLLI entries
delete-gbproxy-tlli NSEI stale purge all stale entries
delete-gbproxy-tlli NSEI imsi IMSI purge entry with the IMSI given
delete-gbproxy-tlli NSEI tlli TLLI purge entry with the TLLI given
