Update the REST API response for get Subcription to include the product SKU value

Update the REST API response for get Subcription to include the product SKU value.

Additional queries are required to retrieve the product SKU which increases the number of api calls and response time needed to get this information.

Product information currently exists in the Get Subscription REST call.  It would be beneficial to have the SKU included in the API response.

Good to hear that it is coming soon :). Is there already a timeline for this?

This is actually already there in the REST API, but our documentation failed to document it.  The field is called productSKU and doc will be fixed momentarily.
