features:
- Add configuration for overlay networks for the docker
network driver in swarm. To use this feature, users need
to create a swarm cluster with network_driver set to 'docker'.
After the cluster is created, users can create an overlay network
(docker network create -d overlay mynetwork) and use it when
launching a new container (docker run --net=mynetwork ...).
