com.rabbitmq.client.QueueingConsumer.nextDelivery()
Main application-side API: wait for the next message delivery and return it. @return the next message @throws InterruptedException if an interrupt is received while waiting @throws ShutdownSignalException if the connection is shut down while waiting
