> We should trigger a global job failover in case of a {{stop-with-savepoint --drain}} fails.
> The situation is obvious in case of the with drain mode. If a savepoint fails we simply can not continue as we have already flushed all data and prepared the state for finishing. We can not simply continue processing records.
> It is more debatable for without drain mode, where we could theoretically continue processing records, however, it is also a good approach to unify the two modes.
> This task is about triggering the failover on the CheckpointCoordinator. We should make sure that if a synchronous checkpoint has been triggered there will be no newere checkpoints scheduled. 
> If a synchronous savepoint fails for whatever reason we should trigger a global failover for the job.
> We might add a safety guards  (checkState calls for situations we missed on the Task in a follow-up ticket)
