Description

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.
