Comment 0 for bug 1668486

Environment:
RHEL + Docker 1.13.1

Reproduce steps:
1. build docker cluster in swarm mode.
2. Create kuryr network in one node, kuryr network will be created as local scope, and we can't see it in other nodes.

[root@limaonew-1 ~]# docker network create --driver=kuryr --ipam-driver=kuryr --subnet 10.225.18.128/26 --gateway 10.225.18.129 --ip-range 10.225.18.128/26 -o neutron.net.uuid=5b231d26-edd8-4536-90e6-be446530b86e limao_input
