    Don't assume default tag exists in container repo

    When no tag is set for an entry in ContainerImagePrepare, the default
    tag from container-images/container_image_prepare_defaults.yaml will be
    assumed, which is typically current-tripleo, or a release version such
    as 16.0.

    In most cases, this tag will exist. However, when using a satellite with
    a content view that has been filtered on tags, it likely won't exist
    since content views are often used with container image versions that
    are not the latest.

    In the case where no tag is set in the entry in ContainerImagePrepare,
    and the default tag does not exist in the container repo, the latest tag
    from the repo will be assumed instead.
