Boot a VM with an unaddressed port

Registered by Rodolfo Alonso on 2019-03-05

(This BP is a copy of https://blueprints.launchpad.net/nova/+spec/vm-boot-with-unaddressed-port)

Currently Nova only allows to boot a VM if all ports attached:
- Have an IP assigned.
- The IP allocation is deferred.

But Nova doesn't allow to spawn a VM with a port without an IP assigned. However, some kind of applications (e.g.: routers) need a port which may be receiving traffic for several addresses, already configured in other devices.

At the moment, Neutron permits to create a port, assigned to a network with the corresponding subnetworks and IP pools, without an IP.

    [WIP] Allow to spawn VMs with port without IP address

We're 1 week from Train feature freeze and this is still sitting with a WIP patch so to focus review efforts for what can realistically land in Train I'm going to defer this. Please re-propose the spec for Ussuri if you plan to pursue it. -- mriedem 20190905

I'll propose a new spec for U with the comments in 641670 addressed and new information. Thanks!! -- ralonsoh 20190805
