Review Comment:
According to offline discussion, we would create a utility method similar to
`ExecNodeUtil.setManagedMemoryWeight` in order to control the usage of
`declareManagedMemoryUseCaseAtOperatorScope` in Flink ML. The weight values
should reference existing values in Flink, like
`StreamExecWindowAggregate.WINDOW_AGG_MEMORY_RATIO`.
