* Replace (deprecate) akka.cluster.auto-down config setting with
akka.cluster.auto-down-unreachable-after
* AutoDown actor that keeps track of unreachable members
and performs down from the leader node when they have been
unreachable for the specified duration
* Migration guide
* Removed leader commands for Shutdown and Exit
* Member shutdown itself when it sees itself as Exiting
* Singleton cluster with status Exiting will shutdown itself,
in case the Exiting gossip never arrives
* Exiting member not part convergence check
* Exiting member is removed by leader (on convergence) when the
exiting member is in the unreachable set, i.e. sucessfully shutdown
* Reverted the change made for #3266, i.e. Exiting is
detected as unreachable again.
* Adjust ClusterSingletonManager to new Exiting behaviour
* Fix bug in HeartbeatSender, which caused it to continue to
send heartbeats to removed nodes, instead of rebalancing
* Refactoring of leaderActions method
* Leaving section in docs
* ClusterCoreDaemon and ClusterDomainEventPublisher can't be restarted
because the state would be obsolete.
* Add extra supervisor level for ClusterCoreDaemon and
ClusterDomainEventPublisher, which will shutdown the member
on failure in children.
* Publish the final removed state on postStop in
ClusterDomainEventPublisher. This also simplifies the removing
process.
* Renamed isRunning to isTerminated (with negation of course)
* Removed Running from JMX API, since the mbean is deregistered anyway
* Cleanup isAvailable, isUnavailbe
* Misc minor
* Major refactoring to remove the need to use special
Cluster instance for testing. Use default Cluster
extension instead. Most of it is trivial changes.
* Used failure-detector.implementation-class from config
to swap to Puppet
* Removed FailureDetectorStrategy, since it doesn't add any value
* Added Cluster.joinSeedNodes to be able to test seedNodes when Addresses
are unknown before startup time.
* Removed ClusterEnvironment that was passed around among the actors,
instead they use the ordinary Cluster extension.
* Overall much cleaner design
* Gossip is not exposed in user api
* Better and more events
* Snapshot event sent to new subscriber
* Updated tests
* Periodic publish only for internal stats
- Created FailureDetectorStrategy base trait.
- Created FailureDetectorPuppetStrategy.
- Created AccrualFailureDetectorStrategy.
- Created two versions of LeaderDowningNodeThatIsUnreachableMultiJvmSpec
- LeaderDowningNodeThatIsUnreachableWithFailureDetectorPuppet
- LeaderDowningNodeThatIsUnreachableWithAccrualFailureDetector
- Added AccrualFailureDetectorStrategy to all the remaining tests - will be split up into two versions shortly.

* Failure detector didn't use hearbeat 1 and 2
* Included heartbeat 2 in ordinary stats
* For heartbeat 1 use guess stats,
important so that connections with only one heartbeat
becomes unavailble, the guess corresponds to 1 second interval
which results in phi > 8 after 18 seconds
* Improved AccrualFailureDetectorSpec
- Renamed all 'frequency' to 'interval'
- Split up NodeJoinAndUpSpec and into NodeJoinSpec and NodeUpSpec.
- Split up MembershipChangeListenerJoinAndUpSpec and into MembershipChangeListenerJoinSpec and MembershipChangeListenerUpSpec.
- Added utility method 'startClusterNode()'
- Fixed race in register listener and telling node to leave
- Removed 'after' blocks
- Cleaned up unused code
- Improved comments
