novaclient supports v4-fixed-ip and v6-fixed-ip as aliases for fixed_ip. As shade used to use novaclient and passed this content through the switch to REST resulted in a behavior regression for shade users. openstackclient also exposes these for the --nics parameter, so it's important that we also support it as we look forward to switching OSC to sdk.
