Right now we expose the kube-apiserver through BGP by adding a static IP address from metal-stack to the machine's lo interface.

This is not suitable for production setups as soon as there are multiple control plane nodes because traffic will be equally distributed across these nodes. A node which is misbehaving will receive network traffic anyway and hence some requests will fail.

An idea could be to utilizing tools like https://kube-vip.io/.
