Please support the new reboot options of dnf-automatic directly

[agross]

dnf-automatic now supports rebooting internally. Please support these configuration items. I'm referring to reboot and reboot_command in the [commands] section.

Thanks, I think this is a reasonable addition.

However, I'm not using this role any longer on my own. So maybe I will not implement this in the near future. (Just added some of the other new config variables, which are easier to support.)

On the other hand, I do accept pull requests. So if anyone wants to give it a try...

That being said, I expect this not being a trivial change. LTS distributions like CentOS probably do not have a recent enough dnf for this feature being supported. The role would need to check this, then either use dnf-automatic's build-in reboot mechanism or the existing workaround otherwise. Preferably both using the existing dnf_automatic_reboot variable to not clutter role's interface. However, we can discuss alternative approaches of course.
