title: Is it possible to specify the client library using swagger codegen?
body: <p>When generating a client based on Swagger metadata, is it possible to specify or configure things somehow that the output should use some other client library? </p>
  
  <p>So if it was a C# client for example, to automatically replace the HttpClient or RestSharp client (I don't recall what it is now as I have not used it in a while) with some custom library?</p>
