Major Hayden fa2800419e Migrate to unique variable names
This patch migrates all of the remaining non-unique variable names
in the security role to a pattern that begins with `security_*`.
This will reduce potential variable collisions with other roles.

This is a breaking change for deployers and users who are moving
from the liberty or stable/mitaka branches to master. Release notes
are included with additional details to help with the transition.

**Opt-in required**
The STIG requires IPv6 to be disabled system-wide unless it is needed for the
system to operate. Deployers must consider how their network is configured
before disabling IPv6 entirely.
To opt-in for this change, set the following Ansible variable to ``yes``:
.. code-block:: yaml
security_disable_ipv6: yes
**NOTE:** This change will go into effect **immediately** on the system and
persist through reboots.
