dnf plugin (or some other means) to simplify repository enablement

[evgeni]

Description

Ohai!

When packit builds a PR, it does so in a copr (packit/{org}-{repo}-{pull_id} by default) and users have to use dnf copr enable packit/theforeman-foreman_maintain-936 (or similar) to get the repo enabled on their system.
It would be cool if instead users could do something like dnf packit enable https://github.com/theforeman/foreman_maintain/pull/936, as that allows to just copy paste the PR URL instead of having to mangle it manually.
Additionally, this would help for PRs that build into a special copr and don't follow the packit/{org}-{repo}-{pull_id} schema.

Over in @theforeman we use Ansible a lot and have a role that can setup packit coprs (if they use the default naming) from PR links for us: https://github.com/theforeman/forklift/blob/master/roles/packit/tasks/main.yml

Benefit

Easier for the users! :)

Importance

I was jokingly mentioning this idea in #packit:fedora.im and people liked it. But certainly not very important :)

What is the impacted category (job)?

Copr builds

Workaround

• There is an existing workaround that can be used until this feature is implemented.

Participation

• I am willing to submit a pull request for this issue. (Packit team is happy to help!)

Or maybe enhance copr plugin? To be aware of Packit behaviour.
