Description

Most of the changes are trivial, due to static changing to non-static. The patch basically adds lifecycle management for shared cache, and uses it to move prewarm to background thread, waiting for prewarm to happen at use time not setConf, and to make init optional (if not called, CachedStore would proxy the methods to rawStore, like it currently does in the ones not implemented).
