title: How to get httpclient response as stream
body: <p>I am using httpclient 4.5.5
  i want to get large files upto 1 gb in response. But it seems like </p>
  
  <blockquote>
    <p><code>CloseableHttpResponse response = httpClient.execute(httpGet);
    HttpEntity entity = response.getEntity();</code></p>
  </blockquote>
  
  <p>This returns whole response so its not good to have whole response in memory. Is there any way to get response as stream?</p>
