Adds supporting CI files

- `.ci.env` will be used in the CI process. It gets renamed to `.env` and contains a basic environemnt so that docker-compose can start the services.
- `build-and-deploy.yaml` will be run by GH Actions. It will build the container images you specify by installing a docker-compose Action and using`docker-compose build --push`.
