Review comment:
       This is needed in upcoming PR to resolve number of consumers of GBK 
transforms, so we can decide whether to materialize the result before sending 
downstream.

> Currently batch translation context uses `currentTransform` for input / ouput 
> lookups, even though we provide a `PTransform` we want to perform lookup for 
> as a parameter.
> We need to introduce a new PipelineVisitor, that would be initialized prior 
> translation and build an in-memory PTransform / AppliedPTransform lookup 
> table, that can be used by translation context.
