title: Change default change detection strategy
body: <p>How to set the default change detection strategy to <code>OnPush</code>? Can it be set globally somehow?</p>
  
  <p>I want to avoid having to adding this line to every component</p>
  
  <pre><code>@Component({
      ...
      changeDetection: ChangeDetectionStrategy.OnPush,
      ...
  })
  </code></pre>
