stasis_cache_pattern: Backport to 13

Browse Source 
Somehow stasis_cache_pattern got out of sync between 13 and master
and it was causing duplicate channel message issues in 13 when
related to a specific endpoint. I.E. from statsd,
'endpoints.PJSIP.1174.channels 0|g' was being emitted twice.

Backporting stasis_cache_pattern from master to 13 solved
the issue and running the unit and testsuite tests confirmed
that no new ones were created.
