default network

[vieux]

I'm not sure I'm reading correctly, but it seems like compose is choosing bridge by default as default network driver : https://github.com/docker/compose/blob/master/compose/project.py#L86

We should let the daemon decide instead, same as this PR moby/moby#17504

I've got a fix in #2295. It works fine against engine. When I run it against swarm, it creates an overlay network, but then I get this failure trying to start the container:
