Enable or Disable the memstore replication from the primary region to the replicas. The
replication will be used only for meta operations (e.g. flush, compaction, ...)
@param memstoreReplication true if the new data written to the primary region should be
                           replicated. false if the secondaries can tollerate to have new
                           data only when the primary flushes the memstore.
