Implement basic terraform deploy for the api-v2 infrastructure

[mikesmit]

The scope of this task is to add terraform for deploying our api-v2 infrastructure. Ideally this would consist of reusable modules (or module) for the application + a project for actual deployment. Similarly the deployment should not be specific to our cloud account (I.e. the make target for deploy should require "us"-specific configuration provided as arguments rather than being hard coded into the repo.

OK now with much more context I think what we want to use, instead of the project factory thing I used last time, is the cloud foundation toolkit

This provides both a bootstrap (for setting up the management account) and a set of terraform modules that wrap the basic GCP modules and implement best practices.
