* 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
