Build dnf and libdnf with packit

[inknos]

Let's consider using packit to build dnf/libdnf.

Actions that packit could takeover:

• [x] Build coprs in PRs
  • [x] createrepo_c
  • [x] dnf
  • [x] dnf5
  • [x] libdnf
• [ ] Run the ci-stack using packit from the source repo of each project
  • [ ] createrepo_c
  • [ ] dnf
  • [x] dnf5
  • [ ] libdnf
• [x] Run the tests from the ci-stack
• [ ] Run propose_downsream jobs
• [ ] Run bodhi updates

Build coprs in PRs:

• Quick to implement, few lines of code

Run tests with tmt:

• Quick to implement
• Some tweaks might be necessary to run dnf/dnf5 tests (currently the tests are set just for dnf5)

Run propose_downsream jobs:

• Tweaks in the specfile are necessary to have a nice changelog
• There might be problems when dnf depends on other components. Manual intervention necessary

Run bodhi updates

• Easy to implement
• Depend on propose_downstream mostly
• Have to be run manually when the previous step is also run manually

The first item, "Build coprs in PRs" is quick to address and will unblock the second part

https://github.com/rpm-software-management/dnf/pull/2023 https://github.com/rpm-software-management/libdnf/pull/1636 https://github.com/rpm-software-management/createrepo_c/pull/409

To run tests from ci-dnf-stack an approach like this should be taken and it will satisfy partially the step "Run tests with tmt and integrate with dnf5 recent changes in testing" https://github.com/rpm-software-management/ci-dnf-stack/pull/1415

The step "Run the ci-stack using packit from the source repo of each project" is covered in these PRs

https://github.com/rpm-software-management/dnf/pull/2034 https://github.com/rpm-software-management/createrepo_c/pull/417 https://github.com/rpm-software-management/libdnf/pull/1639

The step "Run the ci-stack using packit from the source repo of each project" requires a fix for the dnf4 stack
