Subject: Add support for querying the quotas usage
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=775ca024659f8733bf498d0e6a5cf725321bdd29;p=openstack-build%2Fcinder-build.git

Add support for querying the quotas usage

QuotaSetsController's _get_quotas already supports querying for
the usage. This patch allows sending a parameter "usage" to the
REST API when asking for quotas
