Remove use of ansible_fqdn

The ansible_fqdn fact is no longer passed into the individual roles
in order to speed up deployments [0].  This changes alters the role
to use ansible_facts['fqdn'] which is the same.

* Updated tox.ini to include requirements.txt as well
* Updated tox.ini to skip no-changed-when error
