* Improve monitoring and error reporting

#### Container Runtime Interface (CRI)

* [alpha] Add a CRI validation test suite and CRI command-line tools. ([#292](https://github.com/kubernetes/enhancements/issues/292), [@feiskyer](https://github.com/feiskyer))

* [stable] [cri-o](https://github.com/kubernetes-incubator/cri-o): CRI implementation for OCI-based runtimes [[@mrunalp](https://github.com/mrunalp)]
