reedip 9153527252 Return a 404 on quota delete if entry not found
If a tenant quota is not found, the delete operation should fail
with a 404 error. It currently returns 204 even if the delete
operation actually does not delete anything which is inconsistent
with other delete operations in the Neutron API.
