Adds two new flags to alter behaviour in RabbitMQ: * `rabbitmq_message_ttl_ms`, which lets you set a TTL on messages. * `rabbitmq_queue_expiry_ms`, which lets you set an expiry time on queues. See https://www.rabbitmq.com/ttl.html for more information on both. Change-Id: I51ca37ffbb1bb5c07f2d39873f0f33ca20263f2a
