Ian Wienand 5f47584196 yum-minimal: use DNF tools on host
The latest Debian bullseye release doesn't provide yum any more, only
DNF.  This breaks the minimal builds that are using on-host yum tools
to start the chroot.  Probe for yumdownloader, and if it's not there,
use DNF.

Note this requires "dnf download" which may not be packaged.  See
I21cfbd3935e48be4b92591ea36c7eed301230753 for a sample work-around
that installs this plugin in the nodepool-builder container.

===========
yum-minimal
===========
Base element for creating minimal yum-based images.

This element is incomplete by itself, you'll want to use the centos-minimal
or fedora-minimal elements to get an actual base image.

Use of this element will require 'yum' and 'yum-utils' to be installed on
Ubuntu and Debian. Nothing additional is needed on Fedora or CentOS.

If you wish to have DHCP networking setup for eth0 & eth1 via
/etc/sysconfig/network-config scripts/ifcfg-eth[0|1], set the
environment variable `DIB_YUM_MINIMAL_CREATE_INTERFACES` to `1`.

If you wish to build from specific mirrors, set
``DIB_YUM_MINIMAL_BOOTSTRAP_REPOS`` to a directory with the ``.repo``
files to use during bootstrap and build.  The repo files should be
named with a prefix ``dib-mirror-`` and will be removed from the final
image.

If you wish to include extra repositories, set ``DIB_YUM_MINIMAL_EXTRA_REPOS``
to a directory with the ``.repo`` files. The repo files will not be removed
from the final image.

If you are bootstrapping a custom or unsupported OS, and need to install
additional packages to setup the base chroot, set
``DIB_YUM_MINIMAL_BOOTSTRAP_PACKAGES`` to the list of additional packages to
install.
