body: <p>Why is there no async version of CreateDocumentQuery?</p>
  
  <p>This method for example could of been async: </p>
  
  <pre><code>    using (var client = new DocumentClient(new Uri(endpointUrl), authorizationKey, _connectionPolicy))
      {
          List&lt;Property&gt; propertiesOfUser =
              client.CreateDocumentQuery&lt;Property&gt;(_collectionLink)
                  .Where(p =&gt; p.OwnerId == userGuid)
                  .ToList();
  
          return propertiesOfUser;
      }
  </code></pre>
