title: Any way to have initial delay for PeriodicWorkRequest
body: <p>For <code>OneTimeWorkRequest</code>, we can have <code>setInitialDelay</code> to specific the initial delay.</p>
  
  <p>However, there isn't such facility for <code>PeriodicWorkRequest</code>.</p>
  
  <p><strong>Is there any reliable way to achieve so?</strong></p>
  
  <p>One of the less reliable way, is to have a delayed <code>OneTimeWorkRequest</code> worker, to setup <code>PeriodicWorkRequest</code>. However, that's quite cumbersome, and create a possibility, where <code>OneTimeWorkRequest</code> may fail and not able to install <code>PeriodicWorkRequest</code>.</p>
