stages/yum: drop stage

This stage has been replaced by the org.osbuild.rpm stage. The
latter does not need access to network due inside the container
due to its use of the osbuild sources API.

-Depsolves, downloads, and installs packages (and dependencies) using YUM.
-
-Writes the `repos` into `/tmp/yum.conf`, does some tree setup, and then runs
-the buildhost's `yum` command with `--installroot`, plus the following
-arguments generated from the stage options:
-
-* `--releasever={releasever}`
-* `--rpmverbosity={verbosity}`
-* `--config=/tmp/yum.conf`
-
-To prepare the tree, this stage mounts `devtmpfs`, `sysfs`, and `proc` at
-`/dev`, `/sys`, and `/proc` (respectively).
-
-Each repo listed in `repos` needs at least one of `mirrorlist`, `metalink`, or
-`baseurl`. If a `gpgkey` is provided, `gpgcheck` will be turned on for that
-repo, and YUM will exit with an error unless every package downloaded from that
-repo is signed by one of the trusted `gpgkey`s.
-
-Buildhost commands used: `/bin/sh`, `yum`, `mkdir`, `mount`.
