containers: cri-o: kubernetes runc backend

To prepare for native kubernetes support without docker on a target,
we integrate the cri-o incubator project.

cri-o is meant to provide an integration path between OCI conformant
runtimes and the kubelet. Specifically, it implements the Kubelet
Container Runtime Interface (CRI) using OCI conformant runtimes.
The scope of cri-o is tied to the scope of the CRI.

This initial introduction is build + packaging only. It is expected
that configuration and deployment tweaks are done at the distro
level.

+HOMEPAGE = "https://github.com/kubernetes-incubator/cri-o"
+SUMMARY = "Open Container Initiative-based implementation of Kubernetes Container Runtime Interface"
+DESCRIPTION = "cri-o is meant to provide an integration path between OCI conformant \
+runtimes and the kubelet. Specifically, it implements the Kubelet Container Runtime \
+Interface (CRI) using OCI conformant runtimes. The scope of cri-o is tied to the scope of the CRI. \
+. \
+At a high level, we expect the scope of cri-o to be restricted to the following functionalities: \
+. \
+ - Support multiple image formats including the existing Docker image format \
+ - Support for multiple means to download images including trust & image verification \
+ - Container image management (managing image layers, overlay filesystems, etc) \
+ - Container process lifecycle management \
+ - Monitoring and logging required to satisfy the CRI \
+ - Resource isolation as required by the CRI \
