Ramesh Reddy resolved TEIID-1209.
---------------------------------

    Resolution: Done


Cache statistics invove

1) Cache Hit ratio
2) Total number of Requests made against the cache
3) Total number of entries in the cache.

Both for Prepared Plan Cache, and Resultset cache these were added. They can be read through 
1) JOPR on "metrics" panel on the "Data Services". 
2) added a Admin API method "getCacheStats(type)" method.
3) Added support through "Admin Shell" for the "getCacheStats" method.
