    Description

      The WebRuntimeMonitor contains a lot of blocking operations where it retrieves a result from the JobManager and then waits on the future to obtain the result. This is not a good design since we are blocking server threads with that. Instead I propose to follow a more reactive approach where the RequestHandler returns a CompletableFuture of FullHttpResonse which is in the completion handler written out to the channel.
