Do not specify static resource settings in the kubernetes-deployment to avoid unnecessary replacement of pods when the manifest is reapplied (`kubectl apply`). The addon-resizer will dynamically set the pod compute resource values. If the values are also set statically in the deployment configuration, reapplying the configuration will result in the pods getting replaced. Without the static resource, the deployment configuration can be reapplied, and the pods will not be replaced. This change was also made in the upstream kube-state-metrics example manifests. https://github.com/kubernetes/kube-state-metrics/pull/285
