Summary
KindToResource in scrapers/kubernetes/informers.go pluralizes Kind to Resource by appending "s" (strings.ToLower(kind) + "s"). This produces incorrect resource names for Kubernetes types with irregular plurals, causing the dynamic informer to make requests to non-existent API endpoints and retry silently forever.
