title: Is it possible to access the `request` and `response` objects in `functions.https.onCall` Firebase API?
body: <p>I would like to access the <code>request</code> and <code>response</code> objects in <code>functions.https.onCall</code>.</p>
  <p>My use case is that I would like to set cache headers on the response.</p>
  <p>If there is no access to the headers, how are users of this API setting cache for both the CDN and browser?</p>
