This class registers the broker in zookeeper to allow other brokers and consumers to detect failures. It uses an ephemeral znode with the path: /brokers/[0...N] --> advertisedHost:advertisedPort
Right now our definition of health is fairly naive. If we register in zk we are healthy, otherwise we are dead.
