Description

HBASE-11568 allows to use replication to send wal edits from the primary to the replicas.
sometimes the memstore replication is not required, so it will be nice have a flag to disable it.
the result will be more or less the same to what we have in phase-1, but with the row-level consistency provided by the "flush" edit transfered via replication to refresh the hfiles.

create 't1', 'f',

{REGION_REPLICATION => 2, REGION_MEMSTORE_REPLICATION => false}
