    Apply Zun configuration for Docker based on inventory

    If docker_configure_for_zun is set to true, then Zun-specific
    configuration for Docker is applied to all nodes. It should only be
    applied based on the relevant inventory groups. In some cases this can
    cause Docker to fail to start. See
    https://storyboard.openstack.org/#!/story/2008544 for details.

    This change applies the configuration based on the zun-compute and
    zun-cni-daemon groups. It also modifies the expression to not assume
    that these groups exist in the inventory.
