    Remove dependencies on kazoo and friends

    Since kolla-mesos has been retired, there is no need in the code
    base to keep the zookeeper implementation. As a result, just remove
    it. If we were to keep it we need virtualenvs for that part of the
    code base which installs the python dependencies related to it
    for from-binary installs.

    This just simplifies the implementation tremendously and culls dead
    code.
