New Annotation reboot-required

[timo-42]

Hi

We have some workload in the cluster, which can not be moved at will and requires maintenance windows. It would be much easier for our tools to move stuff around if Kured would set an annotation like weave.works/kured-reboot-required=true and we must not fall back to access an Prometheus.

weave.works/kured-most-recent-reboot-needed does not work for us, since it is only set when the reboot process is already started. We need an indicator beforehand, so we don't schedule long running stuff on it and move single instances in their respective maintenance window from the node.

Is this something the community would be interested in?
