Subject: [PATCH] Say hello world and fix IAuthenticationBackend interface
 compliance

- Add hello_world.py that prints "Hello World"
- Remove erroneous `self` param from handle_authentication in IAuthenticationBackend interface definition
- Add handle_authentication no-op default to _BaseAuthBackend so all subclasses satisfy the interface contract
