Updates to the GraphQL references

CartsGraphQLPricing and Discounts
We have made some changes on the GraphQL API that affect referenced resources in product prices, discounts, discount codes, inventory entries and shipping infos.
The reference fields on those resources now support querying for the data stored in referenced objects, similar to Reference Expansion on the HTTP API. The plain reference can now be queried with the corresponding <fieldName>Ref field that has been introduced on the mentioned resources. If you, for example for performance reasons, want to continue using the plain references, you should amend your queries to use the corresponding <fieldName>Ref field instead of the <fieldName> field.
For backward compatibility reasons, the typeId field is still available on the <fieldName> queries, but it is now deprecated. It will be removed from the API after April 2020.
