Sort Services by dependency in Docker compose

[mylastresort]

Hello everyone,

I think this simple feature could be very useful, I'm heavy user of lazydocker, and I use multiple services in a single docker compose project.
Therefore I could facilit accessing the services I might start up in future, for now, I would like to see services sorted by their dependency hierarchy in docker-compose.yml file.

I don't know about the contribution policy here, if anyone knows its possible to create an issue or PR, I would be glad to add a PR.

If anyone is interested about this idea, let me know, so I think about how to actually implement it using BFS, DFS, etc.
