feat: add service_healthy + healthcheck to docker-compose (#811)

* Update docker-compose.yml

Since you use healthcheck anyway, you get to verify that postgres is healthy

* Update README.md

Update the README with 'depends_on: postgresql:  condition: service_healthy'

* Add zipline healthcheck to docker-compose.yml

* Add docker-compose healthcheck for zipline to README.md

* Update docker-compose.yml
