[PATCH v1] block/raw-format: implement .bdrv_get_specific_info handler

[Or Ozeri]

When using the raw format, allow exposing specific info by the underlying 
storage.
In particular, this will enable RBD images using the raw format to indicate
a LUKS2 encrypted image in the output of qemu-img info.
