-// WebSocket live experiment task.
-// It will try the following scenario.
-//
-//  - Fetch |http_url| within |url_fetch_deadline_ms| msec.
-//    If failed, the task is aborted (no http reachability)
-//
-//  - Connect to |url| with WebSocket protocol within
-//    |websocket_onopen_deadline_ms| msec.
-//    Checks WebSocket connection can be established.
-//
-//  - Send |websocket_hello_message| on the WebSocket connection and
-//    wait it from server within |websocket_hello_echoback_deadline_ms| msec.
-//    Checks message can be sent/received on the WebSocket connection.
-//
-//  - Keep connection idle at least |websocket_idle_ms| msec.
-//    Checks WebSocket connection keep open in idle state.
-//
-//  - Wait for some message from server within
-//    |websocket_receive_push_message_deadline_ms| msec, and echo it back.
-//    Checks server can push a message after connection has been idle.
-//
-//  - Expect that |websocket_bye_message| message arrives within
-//    |websocket_bye_deadline_ms| msec from server.
-//    Checks previous message was sent to the server.
-//
-//  - Close the connection and wait |websocket_close_deadline_ms| msec
-//    for onclose.
-//    Checks WebSocket connection can be closed normally.
