Description

Currently we only report "memStoreSize" jmx metric in sub=Memory bean. There are "Memstore On-Heap Size" and "Memsotre Off-Heap Size" in the RS UI. It would be useful to report them in JMX.

In addition, "memStoreSize" metric under sub=Memory is 0 for some reason (while that under sub=Server is not). Need to do some digging to see if it is a bug.
