I'm working on Stackdriver monitoring in another branch, which required updating `google.golang.org/genproto`, which required updating `google.golang.org/grpc`, which required updating `github.com/golang/protobuf`, and so on. This PR updates all of the Google-provided deps to their latest versions. In addition, there is:
- A change in config.go to reflect an updated type name
- Five files changed by `make fmt`
Tested with `make build`, `make test`, and `make testacc`.
* Updated google.golang.org/api/container/v1beta1
* Added support for private_cluster and master_ipv4_cidr
This is to implement #1174. See
