      .Bandwidth limit now applied to instances with VLAN and flat ports with `nmstate` provider

      Previously, in environments using the `os-net-config` `nmstate` provider, QoS bandwidth limit rules were not properly applied to the physical NIC attached to the `br-ex` bridge.

      With this update, the QoS bandwidth limit rules are applied.

      Related to FDP-1472

      With recent changes in edpm-ansible, the default os-net-config provider has been changed from ifcfg to the nmstate provider:
      https://github.com/openstack-k8s-operators/edpm-ansible/pull/908

      After this change, QoS tests started failing on uni04delta-ipv6 job, which tests VLAN tenant networks. BW limit rules are not applied to the physical NIC attached to br-ex.

      One solution to this issue is to resolve FDP-1472.

      But we also believe os-net-config should configure the interfaces associated to the br-ex bridge with `external-ids:ovn-egress-iface=true`. That way, OVN will properly apply the QoS rules to the NIC.

      EDIT:

      This bug also affects VLAN and flat provider networks because the way neutron+ovn applies BW limit to their ports is the same and their behavior has been affected identically.
