res_pjsip: Improve CLI completion performance

Previously, this code would duplicate the target ao2 container and
iterate it for each of the objects within it. For a small number of
objects this was fine, but as the number of objects grows the
performance degrades quickly. For 4000 endpoints, the completion of:

  pjsip show endpoint <tab>

Takes over 10 minutes on my development workstation.

This patch adds a cache of a given command's possible completions in
thread local storage for more performant iteration and retrieval. 4000
endpoints are now completed in under 1 second on my development machine.
