No way to use RPC client from service

1. RPC client cant be defined in service
2. Controller (with defined RPC client) cannot be injected in service to call RCP actions via controller methods
3. Controller cant be RPC client without defining @RequestMapping() on some method (try to remove method with @RequestMapping from controller and in controller constructor call this.client.send() after some timeout, this.client will be null)

Just got example from documentation (Client section) and tried all above. IMHO the most important is 2 issue cause it’s useful to have controllers that works with all transport (http/ws/rpc) things and services for all other work. So service should be able to inject appropriate controller to call RPC client action or send smth away via websocket.

Update. Or maybe we can move RPC client/server to Gateway? They can be injected into anything and rpc has same interaction logic as websocket (ability to receive and send messages).

Since 3.0.0 constructor shouldn’t break RPC client creation. You can inject dependencies through constructor, but interact with them after module init event.
