Review request for hbase.
Summary
-------
See the issue for an overview.
Here is a bit of a synopsis:
+ Region in transition data structure is now kept out in zookeeper to
facilitate master failover and to do away with race conditions that resulted in
double assignment of regions
+ Refactored ZK usage
+ Open and close of regions as well as server shutdown handling and table
transitions are not done in Executors; config. says how much parallellism to
run with
+ New load balancer; features include figuring out the plan on startup and then
assigning out all regions in the one assignment.
+ Most of what passed over the heartbeating mechanism has now moved to go via
zk or the master directly invokes rpc to close/open regions rather than wait on
heartbeat to come around
