Order shipment tracking creation

ChannelEngine shipment tracking is using tracking number object which is not present in Litium system. Because of that tracking information is not available as out-of-box experience via Litium.AddOns.ChannelEngine package. A custom integration has to be created with usage of Litium.AddOns.ChannelEngine.Services.ChannelEngineService.UpdateShipmentTracking method. It is worth mentioning that adding tracking information to shipment may result in shippment closure in ChannelEngine. Once a shipment is closed it may no longer be edited.
