SolrCacheargs map.
The persistence object will exist across different lifetimes of similar caches. For example, all filter caches will share the same persistence object, sometimes at the same time (it must be threadsafe). If null is passed, then the cache implementation should create and return a new persistence object. If not null, the passed in object should be returned again.
Since it will exist across the lifetime of many caches, care should be taken to not reference any particular cache instance and prevent it from being garbage collected (no using inner classes unless they are static).
The persistence object is designed to be used as a way for statistics to accumulate across all instances of the same type of cache, however the object may be of any type desired by the cache implementation.
The CacheRegenerator is what the cache uses during auto-warming to
renenerate an item in the new cache from an entry in the old cache.
