What I really want is https://github.com/GoogleCloudPlatform/kubernetes/issues/2953, but haven't had a chance to code that yet. Maybe it's time. (Then I'd remove the provider-specific test and just say "is it > 0.7.2, or does it claim to be capable of something from the future?" The latter covers the HEAD server case .. though just bumping the server version immediately after release might also accomplish that, too.)
