- We always do the processing asynchronously but maintain a synchronous
API for the implementor of the processor.
- there are a lot of string copies right now. Having a StringPiece
object in grpc++ would really help with that (as we would use it for
C++ metadata).
- Please review the API carefully and if you're happy with it, I'll
proceed with tests.
- Right now it is a global function: would be better to have this per
(secure) port.
- Changed the interface of the auth_context slightly to make it more
friendly.
- Positive tests pass. Still need some work on error case (have a
negative case as well).
- Fixing cpp auth context tests so that they use the shiny new C API.
