REST API response correction

[Jozefiel]

Hi
We are trying to map conductor rest API to GraphQL schemas and facing a problem, that some endpoints return incorrect status codes or bodies.

For example:
POST api/metadata/workflow return status code 200 and without body, but should be 201 with/without body or 200 with the body.
POST api/metadata/workflow return 500, when workflow exists, but should be 409
DELETE api/metadata/workflow// also return 200 but should 204

Is any chance to use recommended status codes?
