    Fix inspect images calls to not use the index format keyword

    Via https://review.opendev.org/#/c/752937/ we added the following code:
           if container_image:
                image_id_str = self.runner.inspect(
                    container_image, "{{index .Id}}", o_type='image')
                if str(image_id_str).strip() != inspect_info.get('Image'):
                    self.log.debug("Deleting container (image updated): "
                                   "%s" % container)
                    self.runner.remove_container(container)
                    return True

    This code works fine in docker:
    [root@controller-0 ~]# docker inspect --type image --format '{{index
    .Id}}' f6ec0f326154
    sha256:f6ec0f326154a80b6844a03c2de2904bbbefea6cdf87acb606ff869ace1a8dd4

    But is problematic in podman (both on 1.6.4 and 2.1.1 versions):
    [root@controller-0 ~]# podman inspect --type image --format '{{index
    .Id}}'
    undercloud-0.ctlplane.redhat.local:8787/rh-osbs/rhosp16-openstack-cinder-volume:16.2_20201110.2-hotfixupdate2
    ERRO[0000] Error printing inspect output: Template parsing error:
    template: image:1:8: executing "image" at <.Id>: can't evaluate field Id
    in type *entities.ImageInspectReport

    This has the side-effect of restarting all containers at each identical
    redeploy.

    We can just drop the 'index' in the query since it works in both docker
    and podman:
    [root@controller-0 ~]# docker inspect --type image --format '{{.Id}}'
    f6ec0f326154
    sha256:f6ec0f326154a80b6844a03c2de2904bbbefea6cdf87acb606ff869ace1a8dd4

    [root@controller-0 ~]# podman inspect --type image --format '{{.Id}}'
