Allow access to server from WebSocket event handlers

[joshkel]

I'm looking for a way to access shared server state from hapi-plugin-websocket's lower-level event handlers (connect, disconnect, and error). For a normal request, I could access this via request.server.app, but that's not an option for these event handlers.

Can/should they be extended to, e.g., offer server or app within the PluginState object or as an additional parameter?
