enable vm boot with unaddressed port

Registered by yalei wang on 2015-10-25

now, nova only could bind with port which has ip and the network with subnet. But it's useless to assign a L3 IP to the port like when it's used as a truck port in a firewall/service VM, and MAC address would be sufficient for this kind of port. VM should be able to bind with this of port.

Neutron has supported that creating a unbind/unaddressed port from a network with or without subnet. But nova could not use this port for now. This spec will make nova remove the limit.

It should not be related to a new attribute of neutron port. Because neutron has announced this unaddressed port in API.
