Docker-compose is not installed by the setup script.

A couple of people have hit the same problem when setting up on Ubuntu. It appears that docker-compose is not part of the docker.io package and needs to be installed separately.

The setup script should install docker-compose too.

I think it is best to get the to install it themselves as we ask them to do with docker. Docker compose comes bundled with the mac docker installer
