[TRAFODION-2303] Limit the heap size of hbase processes for co-operative developer environment

In the developer environment, the HBase processes are started without setting
max heap size.  Then, HBase java processes uses 1/4 of the physical memory as
the max heap size. This results in memory pressure in a cooperative developer
environment shared by many developers.
