title: Async/Await nodejs support?
body: <p>Just a small problem that I can't fix. I'm on Node v8.1.1 and I try to use async/await but it doesn't work. My code snippet looks like this :</p>
  
  <pre><code>const axios = require('axios');
  
  const TOKEN = '...';
  
  const httpClient = axios.create({
      baseURL : 'https://myhost/api/',
      headers : {
          'Authorization': `Token ${TOKEN}`
      }
  });
  
  try {
      const resp = await httpClient.get('users?limit=200');
  } catch(e) {
      console.error(`Fail !\n${e}`);
  }
  </code></pre>
  
  <p>And when I try to run it, I get this error message and nothing happen :</p>
  
  <pre><code>/Users/mathieu/workspaces/galactic-tools/index.js:13
      const resp = await httpClient.get('users?limit=200');
                         ^^^^^^^^^^

  </code></pre>
  
  <p>Async/await should be supported by Node in version 8 directly, right ?
  In the doubt, I tried to run with <code>node --harmony-async-await index.js</code> and <code>node --harmony index.js</code> without result.</p>
