Motivation: The event-bus interceptor chain does not provide a clean way to fail a message interception, some case can be achieved by failing the message itself but that works for limited cases and it does not handle the interception in progress. Cleanly failing a message delivery can be useful in some scenario, specially for testing purposes. Changes: Add a DeliveryContext#fail method that performs a clean fail of the message by interrupting the interception chain and properly failing the message: The message will not make progress anymore and the sender will receive a failure notification whether it is the write future for outbound message writes or the reply handler.
