docker-inspect: Extend docker inspect to export image/container metadata related to graph driver
Export image/container metadata stored in graph driver. Right now 3 fields DeviceId, DeviceSize and DeviceName are being exported from devicemapper. Other graph drivers can export fields as they see fit. This data can be used to mount the thin device outside of docker and tools can look into image/container and do some kind of inspection.
