Both RawStorageDevice and QCow2StorageDevice call next(storage_device_name) in their generate() methods. It would be very useful if this value would be saved in the *StorageDevice attribute, to be available for inspection later.

In tmt, we want to be able to notify test which device belongs to various disks requested via HW requirements. These may have different sizes and properties in general, guessing is much less reliable, therefore reading new *StorageDevice.host_device_path attributes would be very helpful.
