* gpii.oauth2.dbDataStore provides APIs for the authorization server to communicate with the backend
* data storage using CouchDB/PouchDB. CouchDB is used when GPII runs in the production configuration
* and PouchDB is used for the development configuration.
*
* This DB data store is a re-writing of the initial synchronized in memory data store. It now uses
* async promise API to satisfy the async database operations. However, the in memory data store continues
* to serve as a good reference with an much simpler logic. It can be found at:
