ansible-hardening docs are vague about using as standalone

[Major Hayden]

The ansible-hardening docs are a bit vague about how to handle standalone deployments. Questions to answer:

1) How/where to provide variables?
2) What about roles in non standard locations? /home/myuser/ansible-hardening?
3) How do you install via ansible-galaxy from git?
4) What do you need to install first before running the role?
5) What would an inventory file look like?
