cmd/kg/*: sub command peer validation webhook
This commit adds a sub command `webhook` to Kilo.
It will start a https web server that answeres request from a Kubernetes
API server to validate updates and creations of Kilo peers.

It also updates the "Peer Validation" docs to enable users to
install the web hook server and generate the self signed certificates in
the cluster by only applying a manifest.

graph-handler: add missing font to Dockerfile

Dockerfile: remove unnecessary font

This commit leaves Noto as the only font package, as one font package is
sufficient for the container.

cmd/kg: only delete iface if requested
This commit modifies the default behavior of Kilo so that the WireGuard
interface is only deleted on shutdown if explicitly requested.

pkg/wireguard: allow specifying iface named
This commit makes it possible to specify the Kilo interface name. If the
specified interface exists, it will be used; if it does not exist, Kilo
will create it. If the interface already existed, then it will not be
deleted on shutdown; otherwise Kilo will destroy the interface.

manifests,pkg/encapsulation: Flannel compatibility
This commit adds basic support to run in compatibility mode with
Flannel. This allows clusters running Flannel as their principal
networking solution to leverage some advances Kilo features. In certain
Flannel setups, the clusters can even leverage muti-cloud. For this, the
cluster needs to either run in a full mesh, or Flannel needs to use the
API server's external IP address.

*: add complete CNI support
This commit enables Kilo to work as an independent networking provider.
This is done by leveraging CNI. Kilo brings the necessary CNI plugins to
operate and takes care of all networking.

Add-on compatibility for Calico, Flannel, etc, will be re-introduced
shortly.

[0]. Listening on `:8080` will open a dualstack socket on OSs that
