[OVN] ML2/OVN mech driver does not set the OVS bridge name in the port VIF details

[Rodolfo Alonso]

The ML2/OVN mech driver does not set the OVS bridge name nor the datapath type in the Neutron DB port VIF details. Example of an ML2/OVS port:
"""
binding_vif_details: bound_drivers.0='openvswitch', bridge_name='br-int', connectivity='l2', datapath_type='system', ovs_hybrid_plug='False', port_filter='True'
"""

Missing parameters:
* bridge_name
* datapath_type

This information is needed by Nova (os-vif library)

    [OVN] Add the bridge name and datapath type to the port VIF details

    Same as in ML2/OVS, the ML2/OVN mechanism driver adds to the port
    VIF details dictionary the OVS bridge the port is connected to
    and the integration bridge datapath type.

Change abandoned by "Rodolfo Alonso <email address hidden>" on branch: stable/2023.1
Review: https://review.opendev.org/c/openstack/neutron/+/904254
Reason: We can't backport this patch up to 2023.1. Older OVN versions don't have "Chassis_Private" table, as seen in https://ff513c95ce631b00d7e7-2ea4ab35fcc993920ff2033895dde0a5.ssl.cf2.rackcdn.com/904254/6/check/neutron-ovn-tempest-ovs-release-ubuntu-old/373d6f8/controller/logs/screen-q-ovn-metadata-agent.txt
