/**
* This handler does all the heavy lifting for you to run a websocket client.
*
* It takes care of websocket handshaking as well as processing of Ping, Pong frames. Text and Binary
* data frames are passed to the next handler in the pipeline (implemented by you) for processing.
* Also the close frame is passed to the next handler as you may want inspect it before close the connection if
* the {@code handleCloseFrames} is {@code false}, default is {@code true}.
*
* This implementation will establish the websocket connection once the connection to the remote server was complete.
*
* To know once a handshake was done you can intercept the
* {@link ChannelInboundHandler#userEventTriggered(ChannelHandlerContext, Object)} and check if the event was of type
* {@link ClientHandshakeStateEvent#HANDSHAKE_ISSUED} or {@link ClientHandshakeStateEvent#HANDSHAKE_COMPLETE}.
