> Implement the method
>         {{RestClusterClient#cancelWithSavepoint(JobID jobId, @Nullable String savepointDirectory)}}.
> by either taking a savepoint and cancel the job separately, or by migrating the logic in {{JobCancellationWithSavepointHandlers}}. The former will have different semantics because the checkpoint scheduler is not stopped. Thus it is not guaranteed that there won't be additional checkpoints between the savepoint and the job cancelation.
