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 :)

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.

* [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.

When `import_tasks` is used, the task `Fetch OS dependent variables`
always runs, even when excluded by an upstream tag.
When `Fetch OS dependent variables` runs while excluded via tags, it
will always fail with the following.
```
fatal: [alpha]: FAILED! => {"msg": "No file was found when using first_found. Use errors='ignore' to allow this task to be skipped if no files are found"}
