Automatically run all LUKS tests

[poncovka]

It looks like libvirt is not always able to work with encrypted storage and it fails with "no operating system was found on this disk" when it tries to copy out files. We can try to find another way of getting the results from these tests, or we can wait for libvirt to support these use cases.

See: #180, #626

Is it possible to have two disks and one test for encryption and second use without encryption and store the logs there?

That should be doable, but I don't like these kinds of workarounds. They complicate the kickstart file.

Thank you @jikortus, according to the last three nightly runs the issue has been fixed with #1013.
