Deprecated API concerning product availability

LC3 used to have an InventoryService that pulled inventory data via REST API from the commerce system. Because it was causing a performance drop in rendering as top frequent invalidations have occured it was never available for Commerce Hub. Please switch to an approach that is handled in the corresponding commerce system so the data does not need to be pulled from the commerce system by the CAE.
