A resulting model exposes a Headers property with all returned headers

I do not think that we should mess up all models with Header properties. We need to correctly identity the location of the response from server (body or header) and correctly deserialize response from there.

Current implementation of OpenApiClientProvider support only Json responses.

Here we infer response type based on the response code 200/201 and inter result type https://github.com/fsprojects/SwaggerProvider/blob/net5/src/SwaggerProvider.DesignTime/v3/OperationCompiler.fs#L135-L153

Here (assuming that response is always json format and in the body) we deserialize response into expected type https://github.com/fsprojects/SwaggerProvider/blob/net5/src/SwaggerProvider.DesignTime/v3/OperationCompiler.fs#L302-L303

using ProvidedApiClientBase

If you plan to fix this, we need:

• [ ] Add endpoint to Swashbuckle.WebApi.Server that generates similar schema (response in the header with 201 status code)
• [ ] Decide how we will deserialize type from header string to assume that header is formatted as json object.
• [ ] Ensure that fix is implemented for both TPs (Swagger and OpenApi)
