Run AWS and CF API locally

[drewbo]

As a developer, I would like to be able to test all functionality in the local dev environment.

Acceptance Criteria

That story is over-broad but basically I'd like to have localstack + a minimal cloudfoundry API in place as local docker containers so that functions like starting a build, fetching old build logs, get presigned urls, etc, can be run locally

• [x] localstack added locally
• [ ] minimal CF API added locally
• [ ] test that all related functions run correctly

Security considerations

None, local changes only
