KAFKA-5485: Streams should not suspend tasks twice

> Streams should not suspend tasks twice
> --------------------------------------
>
> Key: KAFKA-5485
> URL: https://issues.apache.org/jira/browse/KAFKA-5485
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Affects Versions: 0.11.1.0
> Reporter: Matthias J. Sax
> Assignee: Matthias J. Sax
> Priority: Minor
>
> Currently, Streams suspends tasks on rebalance and closes suspended tasks if
> not reassigned. During close, {{suspend()}} is called a second time, also
> calling {{Processor.close()}} for all nodes again.
> It would be safer to only call {{suspend()}} once in case users have
> non-idempotent operations in {{Processor.close()}} method and might thus
> fail. (cf. KAFKA-5167)
