Add $request_id into the websocket open log.

[qdongxu]

1. In the WebSocket log, $request_id was only applied to WebSocket close log and omitted in the open log. This is inconvenient to trace and analyze.
2. the request field was truncated and the whole line was broken into a new line. when the request size is larger than 60. It's easy to see the request field truncated from the code logic. But I did not find the reason the whole line broke into two lines. but after enlarging the size of the fields, the breaking line problem disappeared too.
