[libvirt PATCH v2 0/6] ci: helper: Rewrite image listing in Python and add stale Docker image checker

[Erik Skultety]

Technically v2 of
https://listman.redhat.com/archives/libvir-list/2021-February/msg00641.html,
but the changes are not minor anymore so I had to change the subject.

since v1:
    - integrated the standalone script to the recently added 'helper' script
    - ditched the hardcode libvirt project ID and instead we work with
      namespacing instead (which is converted to the right URL under the hood)
    - util module moved to the ci/ directory
    - all util functions now use proper Python type hinting
    - ID is now printed along with the stale image name
    - address formatting issues raised

EXAMPLE OUTPUT OF THE REGISTRY CHECKER:

The following images can be purged from the registry:

    ci-debian-9: 1154661
    ci-debian-9-cross-aarch64: 1154667
    ci-debian-9-cross-mipsel: 1154669
    ci-debian-9-cross-armv7l: 1154671
    ci-debian-9-cross-armv6l: 1154676
    ci-debian-9-cross-mips: 1154678
    ci-debian-9-cross-ppc64le: 1154682
    ci-debian-9-cross-s390x: 1154683
    ci-debian-9-cross-mips64el: 1154686
    ci-fedora-31: 1154687
    ci-opensuse-151: 1154724

You can remove the above images over the API with the following code snippet:

    $ for image_id in 1154661 1154667 1154669 1154671 1154676 1154678 1154682=
 \
          1154683 1154686 1154687 1154724; do \
          curl --request DELETE --header "PRIVATE-TOKEN: <access_token>" \
          https://gitlab.com/api/v4/projects/libvirt%2Flibvirt/registry/repos=
itories/$image_id \
      done
