vty: Add 'show ms all' command

This command lists the entries of the ms_store by a line per MS.
Beside TLLI and IMSI, some measurement and state information is
shown.

A ms_list() getter method is added to GprsMsStorage to obtain a list
of the MsGprs objects.

The following VTY command is added to the 'enable' node:

 - show ms all
