Description

With many PipelineRuns based on the same pipeline, it will get confusing if re-runs are named by the pipeline as they will all be named similarly. Losing the distinction between PipelineRuns will cause lots of additional hassles.

Acceptance Criteria

1. Prefix the last run name into the newly created PipelineRun  
2. Validate the existing e2e and add new e2e tests if needed
