Adjust inconsistencies between local-cache and clustered-cache statistics

There are some inconsistencies among MBeans for local and clustered cache:

1)

• local-cache stats: timeSinceReset, elapsedTime
• cluster-cache stats name: timeSinceStart (NO timeSinceReset or elapsedTime stats here)

2) cluster cache now has some statistics that are not available for local cache: CacheLoaderLoads, CacheLoaderMisses, etc. I'm not sure but maybe it would be better to have this consistent.
