I tend to like option B here. Then as versions of Cinder ship, the
'certification' files can go
along with it.

I think this is a good idea as a reference point for users, but I tend to
like the automated mechanism of Option 1b. I see option 1 and 2 being
parallel streams of information. Option 1 being for the cinder
developer team and option 2 being for end users as a quick check to see
what drivers have passed the certification.
I think the general idea of certifying every driver on every milestone is a
good idea, especially since there are several vendors who are running
against master. This mechanism could give them some assurances that
at least the drivers in Cinder are good to go, or are pending
