Stuff on JCache for 3.4 Release [DO NOT MERGE YET, STILL IN PROGRESS AND REFACTOR]

Contains implementations on JCache for 3.4 Release from 3.4 EA release

* Cache recordstore eviction implementation
* Cache recordstore eviction statistics implementation 
@mdogan, My explanation was wrong. They are not using same thread local instance, just using same CacheRecordSortArea class/implementation. They have different instances.
