The Zuul executor contains Ansible 2.13.7 whose 'dnf' module is not
working as it should with Fedora Rawhide because of the DNF5 Change [1].
Unlike DNF4, DNF5 no longer pulls in the python3-dnf RPM, which causes:
TASK [Install RPM packages]
fedora-rawhide | ERROR
fedora-rawhide | {
fedora-rawhide | "msg": "Could not import the dnf python module
using /usr/bin/python3 (3.12.0b3 (main, Jun 21 2023, 00:00:00)
[GCC 13.1.1 20230614 (Red Hat 13.1.1-4)]). Please install
`python3-dnf` or `python2-dnf` package or ensure you have
specified the correct ansible_python_interpreter. (attempted
['/usr/libexec/platform-python', '/usr/bin/python3',
'/usr/bin/python2', '/usr/bin/python'])",
fedora-rawhide | "results": []
fedora-rawhide | }
This adds a workaround that explicitly installs the python3-dnf RPM
using Ansible's 'command' module. It should be removed after Zuul
contains a newer release of Ansible.

Ansible's 'shell' module is almost exactly like the 'command' module,
except that it runs the command through a command line shell so that
environment variables like HOSTNAME and operations like '*', '<' and '>'
work. None of those things are necessary are here. Hence, it's better
to use the 'command' module as elsewhere.
Note that, unlike Ansible's 'shell' module, the 'command' module doesn't
support inline scripts. So, each command needs to be in its own
separate task.

This uses 'skopeo inspect' to get the size of the image on the registry,
which is usually less than the size of the image in a local
containers/storage image store after download (eg., 'podman images'),
because they are kept compressed on the registry. Skopeo >= 1.10.0 is
needed to retrieve the sizes [1].
However, this doesn't add a hard dependency on Skopeo to accommodate
size-constrained operating systems like Fedora CoreOS. If skopeo(1) is
missing or too old, then the size of the image won't be shown, but
everything else would continue to work as before.

This is meant to roughly replicate the build environments used by
downstream distributors to build toolbox(1). These can be restricted in
odd ways compared to a fully featured environment where toolbox(1) is
actually going to be used. eg., the inability to use podman(1) in the
case of Fedora or not having subordinate user and group ID ranges in the
case of openSUSE.
It's important to ensure that toolbox(1) can be built by downstream
distributors without any unnecessary hassle.
