Comment 37 for bug 1396688

I tested amqp_auto_delete with nova.conf and it looks like exchanges and queues have to be recreated by Oslo messaging code, otherwise there are would be errors like:

{amqp_error,precondition_failed,
            "cannot redeclare exchange 'nova' in vhost '/' with different type, durable, internal or autodelete value",
            'exchange.declare'}
