[WIP] Extend error labeling to avoid restart loops.

[StefanRRichter]

This PR draft is a proposal to extend the FailureEnricher mechanism in a way that can be used to avoid restart loops by attaching a certain label to the failure. We pass down the labels into the restart decision and check for the presence of a particular label that this PR introduces.
