2. We should shift command example for "--set" in "fuel network-group help"

root@nailgun ~]# fuel network-group help
...
        To filter them by node group:
            fuel network-group --node-group 1

        Set parameters for the specified network group:
        fuel network-group --set --network 1 --name new_name
