C++ Interceptor for authorization

[Aleksandr Yeganov]

I have a fairly simple use case - check the headers of an incoming RPC call for a special string indicating authorization to use the service. Currently I am experimenting based off of this example https://github.com/grpc/grpc/blob/7bf82de9eda0aa8fecfe5edb33834f1b272be30b/test/cpp/end2end/server_interceptors_end2end_test.cc. Specifically the `LoggerInterceptor` example. The happy path involves calling `Proceed` on the `InterceptorBatchMethods`, but `Hijack` kills the program.

My main question is how do I `fail` the connection when the authorization is not present?

Sincerely,

Aleks
