20130730: I have made a minor modification to my Chaos Moose master node based on
events of this previous weekends tests, the Chaos Moose will now not
kill the current leader if a node is already listed as DEAD, this should
prevent the scenario where the Chaos Moose kills off the leaders one by
one in the event that a node is unable to recover after being failed.
The status of the dead node is then logged into the log file.
