Don't go to the backend for identical cache entry requests
Currently, if an additional request comes in for a cache entry while that same entry is already in the process of being refreshed, we start a duplicate cache update request. This patch adds allows the cache to maintain a hash table of all in-progress requests and queue up multiple callbacks for updates in progress. Once the data is returned, all of these callbacks will fire.
