    Repeat few times put new interface in the namespace

    It seems that from time to time we may experience another variant of the
    shy ovs ports issue (see [1] for details) while trying to put interface,
    e.g. router's port into the namespace by the interface driver.
    To avoid that, this patch adds some repeats of the putting interface in
    the namespace, in the same way like it was done originally with
    set_address of the device.

    Additionally, this patch also refactors a bit part which is responsible
    to set mac address of the device to be able to clean ports in case of
    the permanent error there.
