title: How I can change eslint resolve settings
body: <p>I have project where I use webpack, eslint. Through webpack.config I set to resolve <code>index</code> and <code>Index</code> files. Everything works, except that eslint throws errors <code>import/no-unresolved</code> and <code>import/extensions</code>, it doesn't know, that beside of <code>index</code>, now it should resolve <code>Index</code> files too (<code>import Index from ./components</code>, where in <code>./components</code> have file <code>Index.jsx</code>). My settings below.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
