    [ovn] Implement support for external-gateway-multihoming extension

    The general approach is to update the ovn_client and ovn_db_sync
    code to handle multiple gateway ports wherever a single gateway
    port is handled today.

    In this patch set multiple static routes for default gateway will
    be added by default when multiple gw ports are present. Support
    for the `enable_default_route_ecmp` attribute to control this
    behavior will be added in subsequent patch set to avoid making
    this change too large.
