res_pjsip: Add "like" processing to pjsip list and show commands

Add the ability to filter output from pjsip list and show commands
using the "like" predicate like chan_sip.

For endpoints, aors, auths, registrations, identifyies and transports,
the modification was a simple change of an ast_sorcery_retrieve_by_fields
call to ast_sorcery_retrieve_by_regex.  For channels and contacts a
little more work had to be done because neither of those objects are
true sorcery objects.  That was just removing the non-matching object
from the final container.  Of course, a little extra plumbing in the
common pjsip_cli code was needed to parse the "like" and pass the regex
to the get_container callbacks.

Some of the get_container code in res_pjsip_endpoint_identifier was also
refactored for simplicity.
