upgrade(context:upgradeResponse:)
Called when the upgrade response has been flushed. At this time it is safe to mutate the channel pipeline to add whatever channel handlers are required. Until the returned EventLoopFuture succeeds, all received data will be buffered.

func addCustom(upgradeRequestHeaders: inout HTTPHeaders) Additional headers to be added to the request, beyond the “Upgrade” and “Connection” headers.
