The current implementation of create_cloned_volume calls flatten directly, and this makes whole thread of cinder-volume blocked by that flatten call. This causes heartbeat timeout in RabbitMQ when cloning a volume with rbd backend. This patch makes sure that flatten is executed in a different thread, to allow heatbeat thread to run while flattening a rbd image.
