Automatic merge from submit-queue. If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Add a notice for node e2e config files ref https://github.com/kubernetes/kubernetes/pull/53542 and patched up with https://github.com/kubernetes/test-infra/pull/5107 So while migrating the jobs to prow, I haven't kill the `*.properties` files yet because some lingering jobs, and possibly local tests are still using them. We have a copy of image-config.yaml in test-infra, and all *.properties file is merged into job configs. Add a notice to remind people also update the job configs in test-infra. Also add myself as a reviewer here so I can subscribe some notice. I'll remove them once I cleaned up all legacy files here. /assign @yguo0905 @dashpole @yujuhong
