This prepares for some future changes to blobstore
metadata. For older (pre v3) blobstore disks, we
do not want to try to write new metadata fields,
since in many/most cases, there will not be room
allocated for them.
The current code will keep the existing version -
this is just adding tests to make sure this does not
break in the future.
