class KafkaHealthcheck extends Logging

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.

    When we get a SessionExpired event, we lost all ephemeral nodes and zkclient has reestablished a connection for us.

    When we get a SessionExpired event, we lost all ephemeral nodes and zkclient has reestablished a connection for us. We need to re-register this broker in the broker registry.
