> There are various different ways how a stateful job upgrade can fail.
> For example:
> - Failure/timeout during savepoint
> - Incompatible state
> - Corrupted / not-found checkpoint
> - Error after restart
> We should allow some strategies for the user to declare how to handle the different error scenarios (such as roll back to earlier state) and what should be treated as a fatal error.
