Test reForis guide
This should be a separate test from standard medkit tests as we prefer for minimal setup to do the configuration on our own (as that is faster and more reliable). This means we should boot a new image and try to go through the guide while checking every step that it did, at least partially what it should. We do not have to test the full setup as that should be part of medkit tests. This is just to cover the guide and its stability not to test the router configuration itself.
