No guidance for how to use APQ to do query whitelisting

[benknight]

The Apollo glossary defines query whitelisting as follows:

A technique for preventing unwanted attacks by maintaining a list of approved queries that are allowed in your application. Any query not present in the list that is run against the server will not be allowed. Automatic Persisted Queries is a feature of Apollo Server 2 that enables query whitelisting and persisted queries.

Yet there is no guidance or docs provided at all for query whitelisting using APQ.
