Support for multi-level claim extraction from id_token and access_token

You can now extract custom claims from the id_token and access_token tokens used during the OpenID Connect flow, a method referred to as 'multi-level claim extraction'.

Using multi-level claim extraction, you can set up an API gateway to:

• dynamically select the appropriate authentication server for request authentication
• dynamically select back ends for routing requests
• pass the values extracted from custom claims as headers and query parameters, to a back end
