Finishes quota refactoring by making use of the new quota infrastructure. Partially implements blueprint quota-refactor (the final piece is to remove the old quota architecture). This change is fairly substantial. To make it easier to review, it has been broken up into 3 parts. This is the second part. Change-Id: I1c8b43198f0d44e9e13a45575361aa043fd0639e
