    Set binding profile directly from OVNTrunkDriver (redo)

    Setting binding profile for Trunk subports takes
    time - for 125 subports rally CreateAndListTrunks
    scenario [0] takes about 150 seconds. We need to
    bump up the perfomance because large number of
    subports is widly used in Kuryr deployments.

    To achieve that I changed setting the binding
    profile to be saved directly to the neutron DB.
    Instead calling port_update I update only related
    fields in OVN NorthBound DB rows. That gave performance
    improvement in trunk port creation:

    from 101 sec to 35.6 for 95%ile
    from 99 sec to 34.2 for 50%ile

    The same thing has been done for Trunk deletion.

    This reverts commit 2e0832f7b8bfc31780b657aa0abda4e8b244fbbd
