+ There can only be one RegionTransitionProcedure per region running at a time
+ since each procedure takes a lock on the region.
+
+ <p>The Assign starts by pushing the "assign" operation to the AssignmentManager
+ and then will go in a "waiting" state.
+ The AM will batch the "assign" requests and ask the Balancer where to put
+ the region (the various policies will be respected: retain, round-robin, random).
+ Once the AM and the balancer have found a place for the region the procedure
+ will be resumed and an "open region" request will be placed in the Remote Dispatcher
+ queue, and the procedure once again will go in a "waiting state".
+ The Remote Dispatcher will batch the various requests for that server and
+ they will be sent to the RS for execution.
+ The RS will complete the open operation by calling master.reportRegionStateTransition().
+ The AM will intercept the transition report, and notify the procedure.
+ The procedure will finish the assignment by publishing to new state on meta
+ or it will retry the assignment.
+
+ <p>This procedure does not rollback when beyond the first
+ REGION_TRANSITION_QUEUE step; it will press on trying to assign in the face of
+ failure. Should we ignore rollback calls to Assign/Unassign then? Or just
+ remove rollback here?</div>
