GPUs in Kubernetes Engine now available in beta

This is a great step for running Deep learning training and inference services!

Another good read is the documentation: https://cloud.google.com/kubernetes-engine/docs/concepts/gpu...

Though it looks like it still has some limitations:

- GPUs are only supported for the Container-Optimized OS node image.

- You cannot add GPUs to existing node pools.

- GPU nodes cannot be live migrated during maintenance events.

- GPU nodes run the NVIDIA GPU device plugin system addon and have the DevicePlugins Kubernetes alpha feature enabled.
