    Have zookeeper heartbeat perform basic get

    Under situations where greenthreads are used sometimes
    the kazoo threads can get starved, which can cause bad
    things to happen, so in order to help avoid this have
    the zookeeper drivers heartbeat methods fetch the basic
    namespace (which will cause heartbeats to also be
    flushed and connection verification to happen as a
    side-effect).
