title: How to get the query parameters in nock callback
body: <p>I want to access the query parameter in nock reply callback.</p>
  
  <p>The request object that is exposed contains the path that has them as a string. But I would like to access them as a map so that I will not have to deal with parsing the string</p>
  
  <pre><code>const scope = nock('http://www.google.com')
    .get('/cat-poems')
    .reply(function(uri, requestBody) {
      console.log('path:', this.req.path)
      console.log('headers:', this.req.headers)
      // ...
    })
  </code></pre>
  
  <p>I would expect the query params to be a separate map that I can access
  Does anyone know of a way to achieve this?</p>
