Read the parent name from the results annotation when it's set

[alan-ghelardi]

Closes #231.

Nowadays the Watcher always uses the object's namespace as the parent name
regardless the value of the results annotation. This pull request alters this
behavior by making the watcher to read the parent name from the results
annotation when it's present.

Hi @alan-ghelardi. Thanks for your PR.

I'm waiting for a tektoncd member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
