Automatic merge from submit-queue add optional mutation checks for shared informer cache We need to make sure that no one is mutating caches if they're using a shared informer. It is important that whatever is tracking those changes gets the object *before* anyone else possibly could. This adds the ability to track the original objects in the cache and their current values. Go doesn't have an exit hook or a way to say "wait for non-daemon go-funcs to complete before exit", so this runs a gofunc on a loop that can panic the entire process. It's gated behind an env var. @derekwaynecarr did I get the right spots to make sure that e2e runs with this flag? @smarterclayton @kubernetes/rh-cluster-infra
