Option is None when request gateway ip in swarm mode

[Liping Mao]

In swarm mode, when request gateway ip, the Options are None. It should has the following option {"RequestAddressType": "com.docker.network.gateway"}

I also open an issue in libnetwork to trace this problem:
https://github.com/docker/libnetwork/issues/1702

Here is detail log, you can see the Options are None:

Hyunsun Moon hit similiar problem, and here is the docker version:
Docker version 17.06.0-ce, build 02c1d87

[Hyunsun Moon (hyunsun-moon)]

Looks like RequestAddressType options is set correctly now with the latest Docker version.
See the log below.
