Feature Request: Delete TaskRuns Associated with a PipelineRun

[danielhelfand]

The CLI as of v0.6.0 supports the ability to delete a Pipeline and its associated PipelineRuns as well as the ability to delete a Task and its TaskRuns. We should also add the ability to delete TaskRuns associated with a PipelineRun as part of deleting a PipelineRun.

This was originally thought of as part of #585, which refactored resource deletion for all resources.

I believe this happens automatically when deleting a PipelineRun thanks to the tekton pipeline reconciler, at least from my initial testing:

λ kubectl get pipelineruns
NAME                  SUCCEEDED   REASON    STARTTIME   COMPLETIONTIME
demo-pipeline-run-1   Unknown     Running   7s          

λ kubectl get taskruns
NAME                                            SUCCEEDED   REASON      STARTTIME   COMPLETIONTIME
demo-pipeline-run-1-build-skaffold-app-588ps    Unknown     Pending     1s          
demo-pipeline-run-1-build-skaffold-web-z8fx8    Unknown     Pending     1s          
demo-pipeline-run-1-skaffold-unit-tests-997cv   True        Succeeded   9s          1s

λ tkn pr delete demo-pipeline-run-1
