• Automatically retry metrics:trace_pipeline job

The metrics:trace_pipeline job fails when the jobs API returns nil values for the end time of jobs. Since the jobs have already completed, the nil values are not correct. The solution is just to retry so that the API is called again. This commit sets the job to automatically retry once.
