This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
This PR adds a Kubernetes mixin. It updates the design doc a little to reflect a couple of param changes across the three verbs and harmonizes things using camelCase naming per the [style guide](https://google.github.io/styleguide/jsoncstyleguide.xml?showone=Property_Name_Format#Property_Name_Format) from the GOOG. Closes #82
