Refactor MemStore to implement HeapSize and be externally controlled like LruBlockCache
---------------------------------------------------------------------------------------

                 Key: HBASE-1598
                 URL: https://issues.apache.org/jira/browse/HBASE-1598
             Project: Hadoop HBase
          Issue Type: Improvement
          Components: regionserver
    Affects Versions: 0.20.0
            Reporter: Jonathan Gray
            Assignee: Jonathan Gray
             Fix For: 0.20.1


MemStore needs to be refactored to work more like LruBlockCache now does.

Primarily this will allow the next generation of load balancing to work.  Something at a level
above MemStore and LruBlockCache needs to manage and divide up the available resources of
a regionserver.  The block cache now supports dynamic resizing and parameter configuration.
 Params are also passed in to the constructor, as supposed to being hard-coded / pulled from
confs within MemStore itself.
