> As a first step towards HBASE-2485, this issue is about changing the message flow of
opening and closing of regions without actually changing the implementation of what happens
on both the Master and RegionServer sides.  This way we can debug the messaging changes before
the introduction of more significant changes to the master architecture and handling of regions
in transition.
