Work with Copr team to set up VM image builds

[lbarcziova]

Let's work with the Copr team (@praiskup) and help them set up the VM image build job for their repo.

As a part of this card create follow-up issues if there will be any.

Discussed today with the copr team (@praiskup)

• Here's the current setup: https://docs.pagure.org/copr.copr/how_to_upgrade_builders.html
• We can start with a subset of all the images the Copr team needs.
• Would be beneficial for builders. Mainly for real image builds.
• Would be nice to know if the image can boot.
• Just a set of packages from the Fedora repository is needed. (=No extra repositories.)
• František promised to create an issue on Copr side: VM image builds via Packit & ImageBuilder fedora-copr/copr#3418
  • Resources to be able to play with it.
