This extracts admin kubeconfig generation out of bootkube, now based on
Talos x509 library. On each API request for `kubeconfig`, config is
generated on the fly and sent back on the wire.
This fixes two issues:
* any master node can now generate `kubeconfig` (worker nodes can do
that too, but that should probably change in the future)
* after upgrade-and-wipe the disk scenario, `osctl kubeconfig` still
works

This PR contains generic simple TCP loadbalancer code, and glue code for
firecracker provisioner to use this loadbalancer.
K8s control plane is passed through the load balancer, and Talos API is
passed only to the init node (for now, as some APIs, including
kubeconfig, don't work with non-init node).
