kubeadm join phase
kubeadm join phase enables you to invoke atomic steps of the join process.
Hence, you can let kubeadm do some of the work and you can fill in the gaps
if you wish to apply customization.
kubeadm join phase is consistent with the kubeadm join workflow,
and behind the scene both use the same code.
