The quota feature has three major packages;
- framework/quota
- plugin/database/quota
- usage/*Quota*Impls
Unit test coverage on framework/quota (was not sure how to write tests for
VOs and DAOs, so does not include that):

Unit test coverage on plugin/database/quota: (no explicit tests for API
Response classes except for the response builder impl)

Currently, I'm trying to refactor and write tests for two manager impls in
usage package; coverage jfyi:
