Feature request

Currently in Tekton it is possible define displayName for TaskRun, it would be great to have it for PipelineRun.
PR: #1174

Use case

Using displayName in PipelineRun would allow improve UX of Dashboard. For example if "build" is triggered by GitHub PR it would allow to show PR details (number, author, etc) directly on "PipelineRuns" page.
