Tests names changed

[Matej Marusak]

Hey all,

Today we land [1] which changes tests names.
This affects all opened pull requests as they need to be rebased and also you won't be able to re-run any tests with the same (old) name.
Tests names now have form osimage[/scenario][@owner/project].
So for example:
`verify/fedora-30` is now `fedora-30` (`verify` is default scenario for cockpit-project/cockpit)
`avocado/fedora` is now `fedora-30/avocado`
`selenium/firefox` is now `fedora-30/selenium-firefox` (there cannot be `/` in scenario)
`cockpit/fedora-30@cockpit-project/cockpit-podman` is now `fedora-30@cockpit-project/cockpit-podman` (dropping the `cockpit` prefix)

Hope it makes sense :)
If not or you encounter any problem please ping me on IRC.
