Remove cyclic dependencies between IndexService and FieldData / BitSet caches
Adds a listeners to each of the caches that allows us to remove the dependency on IndexService which is cyclic since the IndexService depends on both of these caches. This cyclic dependency makes testing the indiviual parts very hard and is only added for the sake of incrementing some stats.
