/**
 * Wraps a handler that would normally block and turn it into a non-blocking handler.
 * This is done by calling {@link io.vertx.core.Vertx#executeBlocking(Handler, Handler)} 
 * and wrapping the context to overload {@link RoutingContext#next()} so that
 * the next handler is run on the original event loop
