Support for writing response without returning from WebSocket handler

[shashank-zopsmart]

Current Behaviour

• In order to send response to client, we need to return values, from the WebSocket handler.
• This means that client will again have to make request to get response (if it needs again).
• There can be case when WebSocket handler needs to write response multiple times without having the client need to make request again (as WebSocket provides a simultaneous two-way communication channel over a single connection).

Expected Behaviour

• There should be some exposed method in Context so that response can be written without having to return values from the handlers.
