Ian Wienand 1a5c563920 Run functional tests on Debian Bullseye
We need to update the base reference platform we perform the
functional tests on.  Debian bullseye seems like the best choice -- it
is recent enough to last for a while, and will match the
nodepool-builder container environment.

Depends-On: https://review.opendev.org/c/zuul/zuul-jobs/+/814088

=============
containerfile
=============
Base element for creating images from container files (aka
Dockerfiles).
Usually this element will be called via a more specific distro element
which provides an environment for building a full image. This element
will search active elements for a container file located in
`containerfiles/${DIB_RELEASE}`.
Alternatively, to use this element directly supply the path to a
container file in the environment variable
`DIB_CONTAINERFILE_DOCKERFILE`.
Set ``DIB_CONTAINERFILE_PODMAN_ROOT`` to ``1`` to run `podman` as
`root`.
