Updating the cloud repository

Cloud debugger can now be used to debug errors in production. This debugging functionality requires having a copy of this repo in a Cloud Source Repository.

In order to push the current state of this repository to the Cloud Source Repository for the Chrome Performance Dashboard:

gcloud auth login
git config credential.helper gcloud.sh
git remote add cloud-repo https://source.developers.google.com/p/chromeperf/
git push --all cloud-repo

Note: If the Cloud Source Repository is changed to automatically mirror from the official catapult repository, then this should be unnecessary.
