attempted\hosts

Setting the attempted hosts attribute of a message on ingress will instruct the router to skip the provided hosts when performing a load balance pick.

After routing has completed, the attempted hosts attribute of the message will contain the list of transports (virtual or transport-config) and hosts (tuple) that the message has been routed towards.
