> Currently the AbstractStreamOperatorTestHarness allows for testing an 
> operator when scaling up, through snapshot and restore. This is not enough 
> as many interesting corner cases arise when scaling down or during 
> arbitrary combinations of scaling up and down.
> This issue targets to add this functionality so that an operator can snapshot 
> its state, restore with different parallelism, and later scale down or further up.
