Figure out Cloud Build region story

https://stackoverflow.com/questions/51595900/run-google-cloud-build-in-a-specific-region-and-zone/66829956#answer-66829956

• [ ] What are the pros/cons of using regional Cloud Build
• [ ] How to use regional Cloud Build (how to get the project white listed?)
• [ ] Document these in builds/DEVS.md (and maybe make README.md favour regional)

Edit:

Cannot see any benefit in multi-regional storage for sources, build logs and images.

If no-one replies in the SO (above), create a post in google-cloud-dev group and ask?

Tracked in Google IssueTracker: FR: select build region

It's pretty simple: just use US, unless you have a worker pool set up, in the region.

Cloud Build runs its jobs in us-central1 and there's not really a down side to this, either. It can deploy to any region. Documented in the repo.
