Code Issues Proposed changes

Fix quota calculation for storage test [bug 1715333]

Browse Source 
https://bugs.launchpad.net/kloudbuster/+bug/1715333

Only calculate cinder quota for client tenant
use the storage configs vm count and disk size (not the flavor disk size)

Add INFO to display the calculated disk and volume quotas

Only lookup for flavors ond image once at the kloud level (instead of every instance)
