Add Kubernetes Images for Kolla-Kubernetes

These images are intended to be used with standard Kubernetes deployment
tooling. They are included with Kolla to allow operators to chose the OS
Base image that is used in their environments, and provides Ceph PV support.

+prelude: |
+    Kolla-Kubernetes by default uses Ceph for stateful storage. With
+    Kubernetes 1.5 support was added for Ceph dynamic volume provisioning as
+    requested by claims made against the API server. The images supplied
+    by Google do not include the RBD binary that is required to support this
+    feature.
+features:
+  - Add Kubernetes control pane images with Ceph RBD support.
+issues: |
+    These images will need to be retagged by operators to use with standard
+    Kubernetes deployment tooling such as kubeadm.
