I was blocked on fixes and testing for Flink 1.3.2 at the moment and haven't
started with this yet.
My intention is to start with this issue near the end of the week.
> Allow to rescale JobGraph on JobManager

> Key: FLINK-7124

> In order to support dynamic scaling, the {{JobManager}} has to be able to
> change the parallelism of the submitted {{JobGraph}}. This basically entails
> that we can change the parallelism settings on the cluster side.
> We already have the functionality that we can change the parallelism if it
> was set to {{ExecutionConfig.PARALLELISM_AUTO_MAX}}. Therefore, I think the
> task is mostly about making sure that things really properly work when
> requesting a parallelism change.
