> Stasis caching, in its original incarnation, tightly couples the cache and the caching topic. While this was straightforward, it has a big limitation: since there's only a single caching topic per cache, you cannot subscribe to cache updates per-object.
> This limitation was made evident in res_stasis.c, where the code subscribes to the channel caching topic, but then filters out received messages by channel id. If we were to split caching from the caching topic, then res_stasis can subscribe to individual channel caching topics, which is generally more useful.
> This cleans up res_stasis.c, and is generally a good splitting of responsibilities.
