Research how to provide target-matching environment

[lachmanfrantisek]

There are various issues we are hitting when trying to do tasks on workers targeting another system.

The ideal solution would be to use the exact target instead of having one for all.
In short term, we are going to switch our workers back to Fedora: packit/deployment#613

Spend a while researching the following (and maybe other) options we might want to use:

• Copr / resalloc
  • Already discussed with praiskup, shortly:
    • Either use Copr's own resalloc instance or set up a custom one.
    • Communication via SSH, most of the tooling would need to be implemented.
• Testing Farm
  • Let's chat with TF team to see if we can't reserve an environment there.
• mock
  • mock in a container requires privileged mode which is not possible in our current OpenShift instance
• Container-based solutions
  • Check if containers are enough.
  • We can either enhance the current worker setup and/or use some other service/tool for that.

I believe you can use testing-farm reserve ... to get a OS of your liking, there are already users using it in CI for provisioning systems for Ansible Molecule. While it is not yet a proper API, we are planning to have it a proper supported use case. With the improvements next year in regards to pre-provisioning Daniel will be working on, in the future you could get a target machine very quickly (<30s).
