pjsip_cli: Add pjsip commands 'show registrations' and 'show contacts'.

Added 'show registrations' and 'show contacts' to pjsip cli to make things
a little more consistent.  The output is exactly the same as the list command.

Just needed to add entries to their respective ast_cli_entry structures.
