    [OVN] ovn-db-sync check for router port differences

    Prior to this patch the ovn-db-sync script did not check if the router
    ports were actually out-of-sync before marking them to be updated. This
    behavior introduced irrelevant information in the sync report (specially
    when ran in "log" mode) making the user think that the databases were
    out-of-sync even when they were not.

    This patch adds the code checking for differences in the Neutron Router
    Ports and OVN Logical Router Port entries prior to updating them.

    NOTE FOR THIS BACKPORT:

    The lrp_get() method from ovsdbapp is not present for this stable
    branch, so this patch was adapted to use the get_lrouter_port()
    instead.
