title: How to implement PeriodicWorkRequest chain?
body: <p>I study Android WorkManager, and fond one problem. </p>
  
  <p>I have 2 Works, first of them fetch some data from server and second preload resources (depends on result of first work). I need doing this chains one time per hour.</p>
  
  <p>I need something like:</p>
  
  <pre><code>workManager.beginWith(work1).then(work2)
  </code></pre>
  
  <p>But in WorkManger API I found chain only for OneTimeWorkRequest.</p>
