* Set defaults for internal worker module's count,
machine_type, and os_image
* Allow "pools" of homogeneous workers to be created
using the google-cloud/kubernetes/workers module
* Stop maintaining Kubernetes Dashboard manifests. Dashboard takes
an unusual approch to security and is often a security weak point.
* Recommendation: Use `kubectl` and avoid using the dashboard. If
you must use the dashboard, explore hardening and consider using an
authenticating proxy rather than the dashboard's auth features
