    Allow configuration of DB drivers on docker install

    Added the ability to supply 'pubsub_driver' and 'nb_db_driver'
    parameters to the docker deployment.
    This allows installation with databases different than etcd.
    The default driver is still the etcd one, to maintain backward
    compatibility.
