Request authenticate(Proxy proxy,
                     Response response)
              throws IOException
```
    Returns a request that includes a credential to satisfy an authentication challenge in response. Returns null if the challenge cannot be satisfied. This method is called in response to an HTTP 401 unauthorized status code sent by the origin server.
    Typical implementations will look up a credential and create a request derived from the initial request by setting the "Authorization" header.
    String credential = Credentials.basic(...) return response.request().newBuilder() .header("Authorization", credential) .build();
    Throws:
    
    IOException
