Add support for `extends` feature in Compose v3 / docker stack deploy

As can be seen in https://github.com/docker/compose/issues/4315 , the `extends` feature that exists in `docker-compose` seems to be popular among users despite its flaws. However, it has so far not been added in the Engine's implementation of the Compose format. So far, we have advised users to simply flatten their Compose file structure when using v3, but is this the long-term solution we want to go with? How can we provide a clear upgrade path for users who have come to rely on this feature? cc @dnephin @vdemeester
