title: ESLint rule to disallow if-else statement in single line style
body: <p>I try to find eslint rule to prevent writing if-else in one line style. What should I expect:</p>
  <pre class="lang-js prettyprint-override"><code>// Wrong
  if() /* some code */
  else /* some code */
  
  
  // Correct
  if() {
   /* some code */
  } else { 
  /* some code */
  }
  
  // But for if statement (without else) should be correct both
  if() /* some code */
  if() {
   /* some code */
  }
  </code></pre>
