Leo Gallucci 585f1dc227 Add SUB_UID_MIN/MAX/COUNT, SUB_GID_MIN/MAX/COUNT (#463)
* add SUB_UID_MIN/MAX/COUNT, SUB_GID_MIN/MAX/COUNT

Similar reason as #461

> If /etc/subuid exists, the commands useradd and newusers (unless the user already have subordinate user IDs)
> allocate SUB_UID_COUNT unused user IDs from the range SUB_UID_MIN to SUB_UID_MAX for each new user.
> The default values for SUB_UID_MIN, SUB_UID_MAX, SUB_UID_COUNT are respectively 100000, 600100000 and 65536.

schurzi 29e10e5c3b add tag always to os dependent vars task (#456)
when our collection is used with tags, the os dependent variables are
not resolved. This task should run every time, so the behaviour is
correct.

Colin Adler 8cbeeff501 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.

Felix Herzog eca93cc80b add restart-auditd handler as after configuration change (e.g. of os_auditd_max_log_file_action) you need to restart. Sadly on rhel7 systems you cannot use systemd. And as debian derivates use service as alias and it works I kept it that simple. also adding 'auditd'-tag to make it easy only run that config change if needed.
