This patch applies password quality rules and satisfies the following
controls:
- RHEL-07-010090
- RHEL-07-010100
- RHEL-07-010110
- RHEL-07-010120
- RHEL-07-010130
- RHEL-07-010140
- RHEL-07-010150
- RHEL-07-010160
Each password quality requirement can be turned on/off with variables
and there is one master switch variable that turns them all off. The
master switch is off by default because these rules can cause problems
with existing systems if users aren't aware of the new requirements.
This will be explained in detail in the docs in the follow-on patch.
