Automatic merge from submit-queue (batch tested with PRs 58412, 56132, 58506, 58542, 58394). 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>. don't stop informer delivery on error If an informer delivery fails today, we stop delivering to it entirely. The pull updates the code to skip that particular notification, delay, and continue delivery with the next time. /assign derekwaynecarr /assign ncdc /assign ash2k @derekwaynecarr This would change the "the controller isn't doing anything?!" to "the controller missed my (individual) resource!" ```release-note NONE ``` Kubernetes-commit: 71426ba59fd4a37e5da7deac6298ab33101bb5b6
