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.
```

Due to the new kitchen-ansible version it is now
possible to install ansible on all major OS's via a
ansible omnibus script which is provided by
kitchen ansible. There's no more need to separate
the debian tests.
Also removed whitespace.
This change add the following:
- it checks wether selinux is in "Enforcing" mode
- when selinux is enforcing, it copies a new selinux-policy to the host
- this policy allows sshd to read the shadow-file directly, which is forbidden by selinux otherwise
- the policy is then compiled, a package is created and the policy is installed
- when selinux is enforcing, pam is used and the policy is not disabled, it gets removed,
because its considered a security risk. see here: http://danwalsh.livejournal.com/12333.html
