ccf-0.17.1

Changed

• JS endpoints now list their auth policies by name, similar to C++ endpoints. The fields require_client_identity, require_client_signature, and require_jwt_authentication are removed, and should be replaced by authn_policies. For example, the previous default "require_client_identity": true should be replaced with "authn_policies": ["user_cert"], an endpoint which would like to handle a JWT but will also accept unauthenticated requests would be "authn_policies": ["jwt", "no_auth"], and a fully unauthenticated endpoint would be "authn_policies": []. See docs for further detail.
