* First attempt at OpenIddict
* Making headway and more TODOs
* Redo current policies for multiple schemas + clean up auth controller
* Fix bad merge
* Clean up some more test code
* Fix spacing
* Include AddAuthentication() in OpenIddict addition
* A little more clean-up
* Move application creation to its own implementation + prepare for middleware to handle valid callback URL
* Enable refresh token flow
* Fix bad merge from v11/dev
* Support auth for Swagger and Postman in non-production environments + use default login screen for back-office logins
* Add workaround to client side login handling so the OAuth return URL is not corrupted before redirection
* Add temporary configuration handling for new backoffice
* Restructure the code somewhat, move singular responsibility from management API project
* Add recurring task for cleaning up old tokens in the DB
* Fix bad merge + make auth controller align with the new management API structure
* Explicitly handle the new management API path as a backoffice path (NOTE: this is potentially behaviorally breaking!)
* Redo handle the new management API requests as backoffice requests, this time in a non-breaking way
* Add/update TODOs
* Replace NSwag with Swashbuckle and clean up unnecessary client secret workaround
* Revert duplication of current auth policies for OpenIddict (as it breaks everything for V11 without the new management APIs) and introduce a dedicated PoC policy setup for OpenIddict.
* Fix failing unit tests
* A little niceness + export new OpenApi.json and fix path in contract unit test
* Redo after merge with v11/dev + filter out unwanted mime types
* Remove CreatedResult and NotFoundObjectResult where possible
* Custom schema IDs - no more "ViewModel" postfix and make generic lists look less clunky too
* A little more explanation for generic schema ID generation
* Force Swashbuckle to use enum string names
* Update OpenApi.json to match new enum string values
* Add clarifying comment about weird looking construct
