This implements pushing to and pulling from Kubernetes cluster discovery registry which is simply using extra Talos annotations on the Node resources. Note: cluster discovery is still disabled by default. This means that each Talos node is going to push data from its own local `Affiliate` structure to the `Node` resource, and also watches the other `Node`s to scrape data to build `Affiliate`s from each other cluster member. Further down the pipeline, `Affiliate` is converted to a cluster `Member` which is an easy way to see the cluster membership. In its current form, `talosctl get members` is mostly equivalent to `kubectl get nodes`, but as we add more registries, it will become more powerful.
