[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

Use include_tasks for os_hardening/main.yml (#451)
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"}
```

This brings os_hardening's main.yml in line with ssh_hardening's
main.yml, which doesn't have this issue.
