    ci: Add repo-sanity check
    
    It is somewhat easy to dismiss failed build images as errors in
    the pipeline rather than errors in the repository configuration.
    
    Make a separate check in the review stage testing that the user
    repository is in a state able to run the rest of CI (e.g. generating
    or storing images in its own container registry, since this is
    necessary with ci-templates).
    
    The error message is made known through both junit and CI job output.
