Thoughts on future Kubeadm work required to streamline experience

Currently the kubeadm config and workflow is centered around a single control plane node and any number of worker nodes. This requires additional workarounds when trying to bootstrap and manage clusters with an HA control plane. I believe there is a path forward that would help streamline the effort required to stand up a fully managed HA control plane including etcd.

• Etcd Config Changes
  • Modify the local etcd config to have an additional parameter for exposing etcd ports or to expose the ports by default
  • Add a attribute to override the exposed advertised ip, preferably by choosing an interface to use for detection
• Make API Server Load Balancer config more explicit instead of just overriding the api config
  • Add new attribute to specify a load balancer, which will implicitly set the api config if not explicitly set
• Control Plane join/extend workflow
