If rabbit dies, the consumer can be disconnected before the publisher
sends, and if the consumer hasn't declared the queue, the publisher's
will send a message to an exchange that's not bound to a queue, and
the message wll be lost. Setting passive=True will cause the
publisher to fail and retry if the consumer hasn't declared the
receiving queue yet.
