OpenBSD does not set distributiuon_major_version (#597)
This role fails with `The task includes an option with an undefined variable` on OpenBSD because `distributiuon_major_version` is not set on OpenBSD.

We should either default to "" if the variable is not set, or remove `vars/OpenBSD.yml`. I would prefer the former :)

feat(os_hardening): extend file permission tasks to cover more files (#489)
The tasks `Change shadow ownership to root and mode to 0600` and `Change
passwd ownership to root and mode to 0644` only handle
`/etc/shadow` and `/etc/passwd` respectively. But there multiple
adjacent files that should be handled with these rules as well:

- `/etc/gshadow`
- `/etc/shadow-`
- `/etc/gshadow-`
- `/etc/group`
- `/etc/shadow-`
- `/etc/group-`

This change adds those files to the rules, so that permissions are
handled in the same way.

Closes: #488

[mysql_hardening] Allow setting the mysql_distribution (#473)
* [mysql_hardening] Allow setting the mysql_distribution

On some operating systems, the package for MySQL is not `mysql-server`,
and so the default check for this will not yield the correct result.
This change adds an escape hatch by letting the user set
`mysql_distribution`.  Additionally, it verifies that it is set to a
legal value if the user has set it.

Closes #472
