Subject: [PATCH 15/59] Correction of gossip merge when joining, see #2204

The problem:
* Node that is Up joins a cluster and becomes Joining in that cluster
* The joining node receives gossip, which results in conflict,
  merge results in Up
* It became Up in the new cluster without passing the ordinary leader
  action to move it to Up

The solution:
* Change priority order of Up and Joining so that Joining is used when
  merging

Subject: [PATCH 25/59] Redesign of life-cycle management of EXITING ->
 REMOVED. Fixes #2177.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Removed REMOVED as explicit valid member state
- Implemented leader moving either itself or other member from EXITING -> REMOVED
- Added sending Remove message for removed node to shut down itself
- Fixed a few bugs
- Removed 'remove' from Cluster and JMX interface
- Added bunch of ScalaDoc
- Added isRunning method
