 we should add the following method to BlockDevice interface class.

 then every physical BlockDevice class which implements the interface should also implement this method and return a string 
 representing its type. Furthermore, a nonphysical BlockDevice like SlicingBlockDevice should return the underlying physical 
 BlockDevice type.
