Quota API doesn't return 404 even if passing wrong project_id

[Hirofumi Ichihara]

Quota /v2.0/quotas/project_id API doesn't return 404 even if wrong project_id is passed. It just returns default value when wrong id is passed.

$ curl -g -i -X GET http://127.0.0.1:9696/v2.0/quotas/hoge.json -H "User-Agent: python-neutronclient" -H "Accept: application/json" -H "X-Auth-Token: $TOKEN"

Change abandoned by Hirofumi Ichihara (<email address hidden>) on branch: master
Review: https://review.openstack.org/438335
Reason: Quota itself doesn't manage if project_id is valid. This is not bug.
