shared_lib.sh now contains some more helper functions and the
verification script uses them. Copy it over so that we can source it.
Also install all other dependencies before the actual upgrade.
Since we're sharing functions between test scripts, move greenprint(),
the most rewritten function in the history of the project, to
shared_lib.sh and source it everywhere.
We want to be able to safely gather any artifacts without worrying about
any possible secrets leaking. Every artifacts that we want to upload
will now have to be placed in /tmp/artifacts which will then be uploaded
to S3 by the executor and link to the artifacts will be provided in the
logs. Only people with access to our AWS account can see them.
This test provisions a RHEL-8.6 VM locally, installs osbuild-composer on
it, upgrades the system to RHEL-9.0 and verifies osbuild-composer still
works by building a simple qcow image.
