Fix Cinder's NoValidHostFound errors

Browse Source 
Manila CI jobs create lots of shares and for Generic driver it means
lots of Cinder volumes. After merge of [1] to Cinder project, we started
having NoValidHostFound errors in Cinder logs, it changed default
oversubscription ratio to 1.0 from 20.0. But Manila CI requires it
be bigger than 1.0, so set it explicitly to Cinder's default value 20.0
that is used by all other driver but not LVM.
