Description

As a Beam Playground user, I want to see the execution graph in the Graph tab.

The graph is a representation of .dot format for graphs. DOT representation of the graph can be generated for Java and Python Apache Beam pipelines.

Acceptance criteria:

• gRPC endpoint to retrieve Graph in DOT format implemented on Backend.
• Preparer for java and python code implemented
  • put graph extraction after the last transform (before pipeline.run())
• Graph extraction and storing in GCP added to the CI/CD for precompiled objects
• Graph get from the backend through specific endpoint by pipeline_id
• Graph rendered on frontend 
• Users can see generated graph in the Graph tab after the pipeline was run with the minimal latency
