      Creates the JobGraph corresponding to the provided Pipeline.
      Parameters:
      pipeline - the pipeline whose job graph we are computing.
      configuration - the configuration with the necessary information such as jars and classpaths to be included, the parallelism of the job and potential savepoint settings used to bootstrap its state.
      userClassloader - the classloader which can load user classes.
      Returns:
      the corresponding JobGraph.
      Throws:
      MalformedURLException
