Goal:

• Better handle situations when a package, that we depend on, gets removed from a downstream distribution, that we depend on. By depending on, the following situations are meant (the number 3 is already covered by plan package dependencies):
  1. A package that an osbuild stage depends on is removed.
  2. A package that is in the base package set of an image type is removed.
  3. A package that our tooling directly depends on is removed.

Acceptance Criteria:

• An "Image Builder" step is added to https://issues.redhat.com/browse/RHELMISC-3263, which ensures that our team is notified in case the package to be removed affects our tooling .
• A new "empty" osbuild sub-package "osbuild-stage-deps" is added to the osbuild.spec, which will cover all of the dependencies of all osbuild stages that are relevant for the given distribution.
• The osbuild-stage-deps package is added explicitly to CS / RHEL comps, so that it is pulled into composes.
