specified valid floating IP address doen't work when creating a floating IP

[Chaoyi Huang]

In the neutron API doument "http://developer.openstack.org/api-ref-networking-v2.html", floating_ip_address could be set in the POST/v2.0/​{tenant_id}​/floatingips request. the floating_ip_address is not handled in the source code except checking to see if the floating_ip_address is in the external network or not.

https://github.com/openstack/neutron/blob/master/neutron/db/l3_db.py

the valid specified floating_ip_address is not used during creating port in the external network:

external_port = self._core_plugin.create_port(context.elevated(), {
                'port':
                {'tenant_id': '', # tenant intentionally not set
                 'network_id': f_net_id,
                 'mac_address': attributes.ATTR_NOT_SPECIFIED,
                 'fixed_ips': attributes.ATTR_NOT_SPECIFIED,
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
>>>>>> if the floating_ip_address is valid ip address, it should be used here to create the port in the external network
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
                 'admin_state_up': True,
                 'device_id': fip_id,
                 'device_owner': DEVICE_OWNER_FLOATINGIP,
                 'name': ''}})

I think to create floating IP should respect specified subnet and ip address, just like what we do when we create a port.

There is no support on CLI as well to provide the "floatingip-address", should raise a new bug for this.
