Carl Baldwin 80be86de90 Extension to tell when deferred binding is in effect
This extension exists mainly to let Nova know when deferred port
binding is in effect and its okay for the port to not have any IP
addresses.

The extension is implemented by the segments service plugin with a
very simple implementation to begin with.  This implementation is
likely to evolve.
