Description

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).
