public virtual Task Egress(IAsyncStreamReader<EgressResponse> requestStream, IServerStreamWriter<EgressRequest> responseStream, ServerCallContext context)
Egress streams egress requests and responses. Logically, this is not
actually a streaming request, but uses streaming as a mechanism to flip
the client-server relationship of gRPC so that the server can act as a
client.
The listener, the RPC server, accepts connections from the dialer,
the RPC client.
The listener streams http requests and the dialer streams http responses.
