> 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.
