This fix use `scope=swarm` for service related network inspect. The purpose is that, in case multiple networks with the same name exist in different scopes, it is still possible to obtain the network for services. This fix is related to moby/moby#33630 and docker/cli#167 Signed-off-by: Yong Tang <yong.tang.github@outlook.com>
