* Metadata Agent Improvements ([#66485](https://github.com/kubernetes/kubernetes/pull/66485), [@bmoyles0117](https://github.com/bmoyles0117))
    * Bump metadata agent version to 0.2-0.0.21-1.
    * Expand the metadata agent's access to all API groups.
    * Remove metadata agent config maps in favor of command line flags.
    * Update the metadata agent's liveness probe to a new /healthz handler.

```yaml
defaultNamespace: istio-system
```

and namespaces are specialized for the gateway feature and its components:

```yaml
apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
metadata:
  namespace: istio-operator
spec:
  components:
    ingressGateways:
    - name: istio-ingressgateway
      enabled: true
      namespace: istio-gateways
```

the resulting namespaces will be:

  - kube-proxy addon starts to use the label `node.kubernetes.io/kube-proxy-ds-ready` instead of `beta.kubernetes.io/kube-proxy-ds-ready` as its node selector.
  - metadata-proxy addon starts to use the label `cloud.google.com/metadata-proxy-ready` instead of `beta.kubernetes.io/metadata-proxy-ready` as its node selector.
