Merge pull request #206 from jacobweinstock/another-kubevip-fix

Fix kubeconfig issue with kube-vip:

## Description

<!--- Please describe what this PR is going to change -->

Only the first control plane node needs to use the `super-admin.conf`. All other nodes need to use `admin.conf`. The file: `/run/kubeadm/kubeadm.yaml` is used to determine the first control plane node. This file is used by `kubeadm init` and `kubeadm init` is only run on the first control plane node.

## Why is this needed

<!--- Link to issue you have raised -->
