* Prefer InternalIP and ExternalIP over the node's hostname, to match upstream behavior and kubeadm * Previously, hostname-override was used to set node names to internal IP's to work around some cloud providers not resolving hostnames for instances (e.g. DO droplets)

* Kubelet uses a node's hostname as the node name, which isn't resolvable on DigitalOcean. On DigitalOcean, the node name was set to the internal IP until #337 switched to instead configuring kube-apiserver to prefer the InternalIP for communication * Explicitly configure etcd scrapes to target each controller by internal IP and port 2381 (replace __address__)
