build.golang.org App Engine App

Update with

gcloud config set project golang-org
gcloud app deploy --no-promote -v {build|build-test} app.yaml

or, to not affect your gcloud state, use:

gcloud app --account=username@google.com --project=golang-org deploy --no-promote -v build app.yaml

Using -v build will run as build.golang.org. Using -v build-test will run as build-test.golang.org.
