You need to write a Python function that returns these authorization data structures and then pass that function to the WSGI environment. I have to admit, that it's not easy if you're not familiar WSGI middleware and the topic is too complex to describe it in the MapProxy docs. 

So if you want to use the auth API of MapProxy, you should at first start to play with WSGI and WSGI middleware development.

Yes. It would be a nice feature to have the clipping also work for source coverages.
Patches are welcomed :)
