This modularity means that each role can be installed in a playbook by
itself as long as the other roles exist around it.
This also straps the ensure dependency packages exist in any of the
roles tasks, they should be moved to their own roles and configured
properly if needed.

The testing was failing because the use of the example files with the
same domain names, resulted in the files and the molecule variable were
being merged and therefore running tasks that would fail on test
(example, setting a fake VPN connection that wouldn't start).
