Add volume limits to project overview.

Commit d4b0ab4aa395bf4df2964efcc358100117efdaa0 fixing
bug #1178694 removed volume quotas from project overview.
Cinder is not reporting Snapshot limits today, so that info
can't be added without including quotas again, defeating the
purpose of the original fix.
This fix will only add Volume Qty & Total Storage GB used (including
snapshot size, if any ).
Information is hidden if volume list is empty.
