    Separate config_volume for ringbuilder

    Use a separate config_volume for swift_ringbuilder puppet_config tasks.
    This is necessary so that the swift_ringbuilder and swift-storage
    services don't both rsync files to the same bind mounted directory.

    The rsync command from docker-puppet.py uses --delete-after, so when
    they both use the same config_volume, they can end up deleting the files
    generated by the other (depending on the order of execution).

    Even though a separate config_volume is used, the rings must still end up
    in /etc/swift for the swift services containers. An additional
    container init task is used to copy the ring files into
    /var/lib/config-data/puppet-generated/swift/etc/swift so that they will
    be present when the actual swift services containers are started.
