The StorageManagement class has 2 roles: 1. During boot, it should find all storage controllers in the machine, and then determine what is the boot device. 2. Later on boot, it is a registrar of all storage controllers and storage devices. Thus, it could be used to show information about these devices when implemented. This change allows the user to specify a boot driver other than /dev/hda and if it's connected in the machine - it will boot.
