Sorry, but the backend storage used by Kubernetes in GKE is not exposed, and there are no plans to expose it in the future.
Even if you do have direct access to etcd, I'd strongly recommend using the Kubernetes API for acquiring information like this. The API has various backwards compatibility guarantees, which do not apply to the storage layer. E.g., we just switched to etcd3, and soon we'll be doing a flag flip and start writing a binary data format. The other concern of course is that access to etcd == root on the cluster.
