Supporting the connection of Neutron networks to routers

[Mohammad Banikazemi]

Currently connecting the underlying Neutron networks to routers has to happen out of band. Adding a new option for Docker network create may be valuable.

@vikas no need to push anything to upstream docker. Just passing a router id as one of the options when creating a network should lead to Kuryr hooking up the network to that router.

To do this cleanly, having support for tags [1] for routers in Neutron would be great. Would you look into adding support for tags for routers in Neutron. As of now only networks can have tags [2].
