Comment 18 for bug 1723026

In my understanding, the motivation of this RFE bug is now to retrieve floating IP information and associated port information in one API call. This sounds a reasonable request.

IMHO instead of just adding device_id it is better to return port info as (for example) "port" or "port_detail" attribute of floating IP resource. Note that I don't think we need to include port attributes from extensions and we can start this from the basic port attributes.
