Why isn't AUTH_CONTEXT_KEY a Attributes.Key<AltsAuthContext>?

This because extractPeerObject() returns an Object, rather than AltAuthContext. Internally, we have a different AuthContext class. We need to use share the same API for returning the peer object. Let me know if you have better ideas.

A trick you can do for these is to extend ForwardingServerCall and then implement delegate() to throw like you're doing here. This is fine, though.

Ack on the trick. Let's keep the current FakeServerCall if you don't mind.
