This is the first patch. It works, but I'm not sure about the
implementation. I tried to use the existing Watch. However, as far as I can
tell there are collisions e.g. with exec post handling.

The second patch. This is rather trivial.

The third patch. This is work in progress. Just the variables so far. I
tried to follow other examples. Not sure if I did everything correctly.
And I could not find any place to initialize the rate limiter with the
configured values. They are available when querying via dbus but not in any
initialization function that I could find. Where would I do that?

And can you elaborate reboot, reboot-force and reboot-immediate exactly
mean?
