Motivation: Incorrect WebSockets closure affects our production system. Enforced 'close socket on any protocol violation' prevents our custom termination sequence from execution. Huge number of parameters is a nightmare both in usage and in support (decoders configuration). Modification: Fix violations handling - send proper response codes. Fix for messages leak. Introduce decoder's option to disable default behavior (send close frame) on protocol violations. Encapsulate WebSocket response codes - WebSocketCloseStatus. Encapsulate decoder's configuration into a separate class - WebSocketDecoderConfig. Result: Fixes #8295.
