The nova code would need to be tolerant of the cinder API microversion 
not being available. That could probably use the 
nova.volume.cinder.is_microversion_supported method. The Cinder API 
change would not be backportable though.

I'm assuming you'd start with a cinder spec since it's a versioned API 
change over there.
