Adding a Node to Self-hosted Kubernetes

Self-hosted Kubernetes clusters provisioned with coreos-baremetal's bootcfg can be expanded by adding new server hardware later if you wish. This can be done by adding (copying) new worker install and provisioning groups which match the new server by MAC address. The same worker profile will be re-used (because templating).

Here's what I did after wiring up my snazzy new (ok old) IBM server to join my existing 3 node Intel NUC cluster.
