So how frequently would this be required and when do the results need to 
be provided?
    I generally think this is a good idea, but as well all know that the 
project seems to be in flux at times around the milestones.  Especially 
around G3 when we changed the way the CONF object was accessed, almost 
all drivers failed to work right after G3 when cinder.conf was 
configured with a multi-backend setup.  It took a week or so after G3 
before everyone was able to go through drivers and clean them up and get 
them to work in this scenario. I'm not trying to be a wet blanket on 
this idea, but I think we just have to be careful.   I have no problem 
running my drivers through this and providing the results.  What happens 
when something changes in cinder that causes drivers to fail and the 
test runs fail?   How long does a maintainer get to fix the issue before 
X happens as a result?  Does this happen every milestone I-1, I-2, I-3?  
What happens if a maintainer can't do it for every milestone for 
whatever reason?

Just playing a bit of devil's advocate here.   I do like the idea 
though, just depends on the "rules" setup and how it all applies when 
things don't go well for a particular driver.

Cheers,
Walt
