Allow to extend blobstor with more storage sub-systems. Currently objects stored in the FSTree have empty byte slice descriptor and object from blobovnicza tree have the same id as earlier. Each such change in the identifier formation should be accompanied with metabase version increase. Signed-off-by: Evgenii Stratonikov <evgeniy@nspcc.ru>
