Added
- `default_websocket_close_timeout`, `default_websocket_ping_interval`, `default_websocket_ping_timeout` and
`websocket_close_timeout`, `websocket_close_timeout`, `websocket_ping_interval`
Changed
- `default_websocket_close_timeout`, `default_websocket_ping_interval`, `default_websocket_ping_timeout` default values is 1,
so websockets disconnect very fast, and we recognize "out of sync" very fast.
