Yeah, if using Fog::Network is the only way to do this, an extra configuration variable to enable this might be best. People could keep using `openstack_network_name` like they are now ("Use the address on this network for SSH communication") with the option of implementing something like `openstack_network_nics` to limit what networks are provisioned on the server.

One question: are you using this on a private OpenStack environment, or a public service I could sign up for too (since don't have anywhere I can use this option right now)?
