Quota operations claim to return JSON but do not

[larsks]

Both DELETE /projects/<project_name>/quota and PUT /projects/<project_name>/quota claim to return JSON data (the response has Content-type: application/json, but they are in fact returning plain text:

$ curl -k  -u  admin:pass https://onboarding-onboarding.apps-crc.testing/projects/test-project/quota  -X DELETE
All quota from test-project successfully deleted

And:

$ curl -k  -u  admin:pass https://onboarding-onboarding.apps-crc.testing/projects/test-project/quota  -X PUT -d '{"Quota": {"QuotaMultiplier": 1}}'
MOC Quotas Replaced
