[backport] [FLINK-5114] [network] Handle partition producer state check for
unregistered executions
This is a backport of #2912.
Code between 1.1 and 1.2 slightly changed. I decided to further backport
the new callback method via `TaskActions`.
This would be important to get into 1.1.4.

[FLINK-5114] [network] Handle partition producer state check for

> Reporter: Ufuk Celebi
> Assignee: Ufuk Celebi
>
> If a partition state request is triggered for a producer that finishes before
> the request arrives, the execution is unregistered and the producer cannot be
> found. In this case the PartitionState returns null and the job fails.
> We need to check the producer location via the intermediate result partition
> in this case.
