  // When a driver is initialized on a node, it provides the same topology keys
  // along with values. Kubelet will expose these topology keys as labels
  // on its own node object.
  // When Kubernetes does topology aware provisioning, it can use this list to
  // determine which labels it should retrieve from the node object and pass
  // back to the driver.
  // It is possible for different nodes to use different topology keys.

- plugin config "exclude namespaces" applies first
- ambient is enabled if:

    - pod label "istio.io/dataplane-mode" is not "none"
- sidecar interception is enabled if:

Kubeadm: apply `second stage` of the plan to migrate kubeadm away from the usage of the word `master` in labels and taints. For new clusters, the label `node-role.kubernetes.io/master` will no longer be added to control plane nodes, only the label `node-role.kubernetes.io/control-plane` will be added. For clusters that are being upgraded to 1.24 with `kubeadm upgrade apply`, the command will remove the label `node-role.kubernetes.io/master` from existing control plane nodes. For new clusters, both the old...

     * Spec change:
        * Deployment’s [selector](http://kubernetes.io/docs/user-guide/labels/#label-selectors) is now more general (supports set-based selector; it only supported
equality-based selector in 1.1).
        * .spec.uniqueLabelKey is removed -- users can’t customize unique label key --
and its default value is changed from
“deployment.kubernetes.io/podTemplateHash” to “pod-template-hash”.
