Description

The ULR currently doesn't provide support for the Message channel in the JobApi. This feature is very useful for diagnosing problems in failed pipelines and is pretty important for Python ValidatesRunner tests, so it should be added. Flink currently supports this, so it could be used as a starting point for how to implement this.
