Implement handling for metadata version 2. The new metadata adds a label and UUID for the device mapper device, and additional UUID for the underlying block devices. It also allows for an additional regular drive to be used for emulating random access zones. The emulated zones will be placed logically in front of the zones from the zoned block device, causing the superblocks and metadata to be stored on that device. The first zone of the original zoned device will be used to hold another, tertiary copy of the metadata; this copy carries a generation number of 0 and is never updated; it's just used for identification.
