Kube-Node / NodeSet

kube-node is a minimalistic API which enables Kubernetes to manage its nodes by itself. The goal is to have a higher abstraction layer for managed k8s nodes and to be able to integrate Kubernetes with different providers in a generic way. It is intended to live outside of core Kubernetes and add optional node management features to Kubernetes clusters.
