This class handles zookeeper based leader election based on an ephemeral path. The election module does not handle session expiration, instead it assumes the caller will handle it by probably try to re-elect again. If the existing leader is dead, this class will handle automatic re-election and if it succeeds, it invokes the leader state change callback
