Thanks for the feedback [~azagrebin]
Then let's take that simple way and refactor it later when we are ready to 
introduce WeightedResourceSpec.

> To calculate managed memory fraction for an operator with UNKNOWN resources, 
> we need to know whether the operator will use managed memory, according to 
> FLINK-14062.
> To achieve this, we need an interface to set/get whether an operator uses 
> managed memory. It can be part of {{ResourceSpec}} or directly locates in the 
> operator description classes ({{Transformation}}/{{StreamNode}}).
