Set up integration with Fedora CI

[siteshwar]

This issue tracks integration with the Fedora CI. Each pull request opened on https://src.fedoraproject.org/ should go through a differential scan with target branch as the base. This would give the defects that may be introduced by the changes in the pull request.

@nirik Please add if I missed anything.

There is some discussion going on about changing the workflow for pull request testing in Fedora. I would keep this issue on hold until we have a clear idea about how to go forward.

Hello,

with Packit, once we have packit/packit-service#2453, we can provide the very same functionality we have for upstream projects... We should have a basic prototype of running on dist-git PRs by the end of the year but having OSH integrated would still take more time.
