sgsn: Add VTY commands to manage subscriber cache
This adds the following commands to the ENABLE node: - show subscriber cache - update-subscriber imsi IMSI insert authorized (0|1) - update-subscriber imsi IMSI cancel - update-subscriber imsi IMSI commit These commands are mainly testing tools and maintenance helpers. The update commands work asynchronously and can be used to complete a pending update request or to terminate an existing connection. The 'insert' command just update the subscriber records but does not notify the GMM layer. Invoke the 'commit' command to continue with pending procedures. Note that the subscriber cache is not stored persistently and will always be empty after an SGSN restart. Sponsored-by: On-Waves ehf
