Print services in dependency order 

Currently, `compose config --services` outputs the services in
a random/non-deterministic order.

In Compose v1, this was implicitly topologically sorted because
the project services were pre-sorted. With `compose-go`, the
services are unordered, and the `WithServices()` helper can be
used to iterate in dependency order.
