Summary
-------
Just putting this up to show people. It's not done but the balanceCluster()
method "works" and has a bunch of test cases.
This addresses bug HBASE-2697.

> Key: HBASE-2697
> URL: https://issues.apache.org/jira/browse/HBASE-2697
> Project: HBase
> Issue Type: Sub-task
> Components: ipc, master, regionserver
> Reporter: Jonathan Gray
> Assignee: Jonathan Gray
> Priority: Critical
> Fix For: 0.21.0
>
>
> This issue is doing the meat of what HBASE-2485 is about and continues what
> was started in HBASE-2694 after some code cleanup to make life easier.
> This deals with no longer piggybacking messages from Master to RegionServers
> on heartbeat responses and instead sending direct unsolicited messages. This
> also deals with moving the open/close logic fully into handlers and removing
> the existing open/close code on both the RS and M sides. There may also be
> some changes to the master in-memory state of regions in transition. The new
> load balancer will probably be introduced with this issue but not fully
> integrated yet.
