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`.
* Vendor cloud logging api
* Add logging sink support
* Remove typo
* Set Filter simpler
* Rename typ, typName to resourceType, resourceId
* Handle notFoundError
* Use # instead of // for hcl comments
* Cleanup test code
* Change testAccCheckLoggingProjectSink to take a provided api object
* Fix whitespace change after merge conflict
