This works, but with some caveats. It won't work with any path
other than /usr/bin for the executable (there's no step where
you can substitute another bindir into the .service files) and
there is no uninstall possible. You can use 'pip uninstall' to
remove things installed with 'setup.py install', but this won't
catch stuff installed via data_files; if you 'pip uninstall
fedora-openqa' the systemd files stick around.
The alternative would be to set up a Makefile, I guess, which
would puppet setup.py. I'm not sure how desirable that is and
how much we care about the above issues.
I think that we should also notice user that he need to either reboot or run sudo systemctl start openqa-trigger-current.timer.
