Currently the flag 'authenticate' is managed per subscriber.
This patch replaces that flag by a global cfg.require_authentication
flag that enables/disables the use of the Auth & Ciph procedure for
every subscriber. The flag is set by the VTY, if and only if the
authorization policy is 'remote'.
The VTY command
- update-subscriber imsi IMSI insert authenticate <0-1>
is removed.
