Feature requested: Websocket support open with params

[qZhang88]

The open function of WebSocketClient does not support param, could that be supported? I think the change is small.

change function definition from

int open(const char* url, const http_headers& headers = DefaultHeaders);

to

int open(const char* url,
         const http_headers& headers = DefaultHeaders,
         const QueryParams& params = QueryParams());

update implementation with one line, just set query_params before ParseUrl

+    http_req_->query_params = params;
     http_req_->ParseUrl();

可以在open前通过setHttpRequest接口来设置http_req_的

明白。嗯，不过我是直接把param拼接到url，也是一样的。
