The problem is that the kubelet kubeconfig gets created early, but the
actual client key and cert files are not written, so controllers spam
with scary errors that the config is not valid. This PR removes those
scary messages as we wait for the kubeconfig to be usable.

* calculate covering IPPrefixes for the KubeSpan peer `AllowedIPs`,
check for overlap
* don't use KubeSpan IP as potential node endpoint (inception!)
* allow Wireguard config to be applied which doesn't change peer
endpoint
* support for pre-shared Wireguard peer keys

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.
