Support for dynamic fields?

Hey there, DRF docs looks really cool. But it looks like the project doesn't currently have support for viewsets that implement a `get_serializer` method. In my case, I use information from the request (specifically the token scopes) to determine the fields available to the client. This means that it's an error to instantiate a serializer without providing a request variable in a `context` kwarg. And DRF-docs does exactly this in `api_endpoint.py:50`

Is there any way I can override the methods that determine fields to show? Thanks!

Start by reading api_endpoint.py:50 and tracing how viewsets using get_serializer are handled, especially serializer construction and the request context. Done means the project has a documented, supported way to accommodate serializers whose available fields depend on request token scopes, with the override point clearly identified.
