Copr/Koji tmt plugin - Githubissues

Goal

Have a plugin for creating copr/koji reverse dependency testing

[ ] plan.discover: Create tests that would run copr/koji builds
- packages: Packages for which to run fedrq wr ${packages}/fedrq wr --src ${packages} (it seems to give union instead of intersect)
- spec_file: Alternative to the above that generates all packages from the spec file
- ...: Other args to be passed to generate the test framework with
[ ] test.framework: Main test interface running copr/koji build
- user/group: copr user or group to which to submit the build
- project: copr project where to build in
- from_dist_git: Create copr build using the distgit repo's spec file
- For koji, the builds would just be --scratch
[ ] Authentication: Could be handled manually by a prepare step or by the infrastructure testing-farm/github secrets
[ ] How to include the current build?
- Manual via copr, assume this is already setup in the user/group/project variables
- koji_build/copr_project: variables pointing to where the local build was created
- testing-farm and packit provide the information of where the build was made, but it would hard-code the integration there

Integration with upstream/downstream: E.g. building in side-tag, specifying dependent git repo/branch
Chaining testing-farm executions such that the integration tests are run for upstream
Packit interface to use in test.framework
Create copr build from packit.yaml if downstream or upstream contains the configuration
Equivalent integration for local build with mock

Such plugins should be incorporated outside of main tmt, because the dependencies on copr/koji interface could be problematic for non-Fedora packaging environments, especially since many of those dependencies would have compiled libraries. Well I guess having it as optional-dependencies would also work :thinking:, but the testing could be quite crowded

Thoughts on the potential integration? @lachmanfrantisek @thrix
