Support creating unaddress neutron port

[hongbin]

It is desirable to be able to create an unaddress neutron port. Right now, it seems this is unsupported in CLI.

The use case is outlined in this spec: https://specs.openstack.org/openstack/neutron-specs/specs/liberty/unaddressed-port.html

    Support creating unaddress neutron port

    Introduce an option '--no-fixed-ip' on port create command.
    If this option is specified and '--fixed-ip' is unspecified,
    OSC will send a request to neutron with 'fixed_ips' as an empty
    list, which will create an unaddress neutron port.

    Note: The use cases of unaddress port was outlined in:
    https://specs.openstack.org/openstack/neutron-specs/specs/liberty/unaddressed-port.html

    (dtroyer: add Depends-On for Zuul v3 test)

[Akihiro Motoki (amotoki)]

The feature is implemented in OSC and neutron CLI is in the feature freeze phase, so Won't Fix in neutronclient.

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/python-openstackclient 3.13.0 release.
