Deprecated: Use OrderUpdate.update_mask instead. If type = SNAPSHOT, OrderUpdate.order
should be the entire order. If type = ORDER_STATUS, this is the order level status
change. Only order.last_update_time and this vertical status are picked up. Note:
type.ORDER_STATUS only supports PurcahaseOrderExtension status updates and there is no
plan to extend this support. Instead, we recommend using update_mask as it is more
generic, extensible and can be used for all verticals.
