Response Status Codes are not the Codes defined in spec

[cebe]

cebe#3

According to the OAS 3 Spec, status codes that are available are defined in
https://tools.ietf.org/html/rfc7231#section-6

The generated code is returning 422 for example.
https://github.com/OAI/OpenAPI-Specification/blob/3.0.2/versions/3.0.2.md#httpCodes

These code is not defined in the RFC.
If i am correct it should return 400 instead.

Or for duplicate errors: 409

not sure how to solve this, at least for the CRUD generator the codes are defined by the actions and not by the spec.

For CRUD actions (RestAction/FractalAction) this is not simple. Lot of changes in this lib and maybe few change in Yii framework (422 in Yii is hard-coded. It should be made configurable) will be required.

PR #95 add docs to custom action that the action should return one of the HTTP response status code mentioned in OpenAPI spec
