* Adjust size of recorder LRU based on number of entities
If there are a large number of entities the cache would
get thrashed as there were more state attributes being
recorded than the size of the cache. This meant we had
to go back to the database to do lookups frequently when
an instance has more than 2048 entities that change
frequently
* add a test
* do not actually record 4096 states
* patch target
