If the job is in a terminal state, the coordinator will be `null`ed as well.
> Implement cancelWithSavepoint in RestClusterClient

> Key: FLINK-8459
> URL: https://issues.apache.org/jira/browse/FLINK-8459
> Project: Flink
> Issue Type: Sub-task
> Components: Client
> Affects Versions: 1.5.0
> Reporter: Gary Yao
> Assignee: Gary Yao
> Priority: Blocker
> Labels: flip-6
> Fix For: 1.5.0
>
>
> 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.
