Improved readability and consistency

* Noted that our Python package should probably be installed system-wide.
* Changed hostname references to user-laptop to db-server since ari-backup has been known to be troublesome for backing up laptops.
* Removed some extra whitespace in the config examples to be more consistent with our other config examples.
