Update all the packages under google.golang.org/api to use the same
commit. This is a necessary precursor for using Go modules.
There is a breaking API change in the clients, but it's a one line
change. As such, Travis will say this doesn't build. I've verified after
the one line change, it will run the unit tests. That change needs to be
made in MM, however. Once this PR is merged, a PR against MM will be
opened.
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`.
