pjsip_options: show/reload AOR qualify options using CLI

Currentrly pjsip_options code does not handle the situation when the
AOR qualify options were changed.

Also there is no way to find out what qualify options are using.

This patch add CLI commands to show and synchronize Aor qualify options:
pjsip show qualify endpoint <id>
    Show the current qualify options for all Aors on the PJSIP endpoint.
pjsip show qualify aor <id>
    Show the PJSIP Aor current qualify options.
pjsip reload qualify endpoint <id>
    Synchronize the qualify options for all Aors on the PJSIP endpoint.
pjsip reload qualify aor <id>
    Synchronize the PJSIP Aor qualify options.
