This should resolve two problems:
* Ansible cannot find `userdata.j2` due to incorrect path used
* Allow the template to be actually rendered as template instead of
being loaded as plain file without evaluation
There's another solution - simple move of `/roles/apply/templates/`
to `/roles/apply/files/templates/`. I have favored this one though
to make it possible to use Jinja2 expressions in the template file,
which I believe was the original creator's idea.
