 Note: Due to [two](https://github.com/kubernetes/kubernetes/issues/83778) [bugs](https://github.com/kubernetes/kubernetes/issues/86359) in Kubernetes v1.16.1, and prior to Kubernetes v1.16.5 the kube-prometheus release-0.4 branch only supports v1.16.5 and higher.  The `extension-apiserver-authentication-reader` role in the kube-system namespace can be manually edited to include list and watch permissions in order to workaround the second issue with Kubernetes v1.16.2 through v1.16.4.
