   JIRA: [NEMO-183: DAG-centric translation from Beam pipeline to IR DAG](https://issues.apache.org/jira/projects/NEMO/issues/NEMO-183)
   
   **Major changes:**
   - Implemented DAG-centric translation from Beam pipeline to Nemo IR, which consists to the two phases:
     - **PipelineVisitor** traverses through the given Beam pipeline to construct DAG of Beam transforms, while preserving the hierarchy of CompositeTransforms.
     - **PipelineTranslator** defines not only mappings between PrimitiveTransform and IRVertex, but also correspondneces between CompositeTransform and TranslationContext, based on which PipelineTranslator can tune translation behavior.
   
   **Minor changes to note:**
   - N/A
   
   **Tests for the changes:**
   - Modiifed existing tests to match the topological ordering produced by the new visitor.
