Bug fix binge
Bunch of minor bugs that have been kicking around for a while have been fixed.
- Role no longer manages /var/run directory.
- Warnings under Ansible 2.3 resolved.
- Added a note about RHEL 7 and UsePAM to the variables file.
- Removed a cyclical symlink in the tests/roles directory and reworked the dev Vagrantfile accordingly.
This does change functionality, hence the bump to 0.5
