402757 - WebSocket client module can't be used with WebSocket server module in the same WAR.

Introduced a shaded artifact that relocates the websocket-common classes, so they cannot
be shared with the server.
The shaded artifact has classifier "hybrid", and users will need to exclude the websocket-common
dependency manually when using the classified artifact.
