Previously limit information was always retrieved but it is not used in the admin overview. This commit moves the limit related logic into a separate class ProjectUsageView. testing of usage.views is covered by individual panel tests, so UTs for panels which uses UsageView rather than the new ProjectUsageView need to be updated in this commit. blueprint make-quotas-great-again Change-Id: Id93b66d11e3b0c98d1fbb0454bb43984c2999d92
