JCLOUDS-526 proposes the removal of the legacy Nova QuotaClassApi, however the QuotaApi currently maps to the "os-quota-class" OpenStack Nova Extension.
The domain object for Quota needs to be updated to reflect the added/removed fields.
volumes, gigabytes, and cores have been removed.
quota_set, fixed_ips, and injected_file_path_bytes have been added.
Unit/Live Tests will need to be updated
