WebSocketClientProtocolHandler: add option to disable UTF8 validation of text frames.
Motivation:
WebSocketClientProtocolHandler unconditionally adds UTF8 validation handler, even if one is not necessary (e.g. text frames are not used by application).
Modification:
add WebSocketClientProtocolConfig.withUTF8Validator option.
WebSocketClientProtocolHandler uses .withUTF8Validator option when adding Utf8FrameValidator to channel pipeline.
Result:
configurable UTF8 validation of text frames payload in WebSocketClientProtocolHandler.
