Fix issue with virtual ports not being exposed on time
The requested-chassis information is only added by neutron for "" port types. The virtual ports chassis is decided by OVN not by neutron, and neutron only update that information in the periodic maintenance task. As part of [1] information about the virtual port chassis is being added to the external_ids, as well as for "" ports. This patch is adapting the NB DB driver to consume this new source of information and being able to expose those ports when OVN associates them to a node. Depends-On: https://review.opendev.org/c/openstack/neutron/+/882705 Closes-Bug: #2020157 [1] https://review.opendev.org/c/openstack/neutron/+/882705 Change-Id: I9abf987004370d0c3ec6a152bb28ab450a9af2c2
