Add support for docker-compose

Can we add support for docker-compose via docker stack?
That way we would have:
1) Kubernetes manifests
2) Helm
3) Docker-compose

1, 3 are ideal for developers.

`docker stack deploy` is pretty much exactly like `helm install`. Uses a compose.yaml instead of Helm charts.
https://docs.docker.com/engine/reference/commandline/stack_deploy/#description

No file, test, or entry point is named. Start by tracing the existing Kubernetes manifest and Helm deployment paths, then compare their behavior with the linked docker stack deploy documentation. Done means developers can deploy through a compose.yaml using docker stack while preserving the existing deployment options.
