title: Modify the src location for javascript script tags during ng build
body: <p>My index.html file post ng build has the below files </p>
  
  <pre><code>&lt;script type="text/javascript" src="inline.bundle.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="polyfills.bundle.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="styles.bundle.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="vendor.bundle.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>How can I make angular cli prepend 'app' in the src folder location, for example <code>src="/app/vendor.bundle.js"</code></p>
  
  <p>I would need to make the above change since I am loading all my static assets in dropwizard from a file system location starting with '/app/'</p>
  
  <p>Below is my angular-cli.json for reference</p>
