This PR will add the fail status to the pipelineloop customrun when it failed/cancelled. Previously we only update failing states for each iteration pipelinerun dag.

The next phase for this is to merge the pipelineloop driver/publisher tasks into the controller itself. The previous PR only merge for each iteration dag but not the main pipelineloop object dag.
