title: Work grouping/chaining for WorkManager similar to android-priority-jobqueue
body: <p>We are migrating to <a href="https://developer.android.com/topic/libraries/architecture/workmanager" rel="nofollow noreferrer">WorkManager</a>, the successor of <a href="https://github.com/yigit/android-priority-jobqueue" rel="nofollow noreferrer">android-priority-jobqueue</a> library. How can we implement work <a href="https://github.com/yigit/android-priority-jobqueue/wiki/Job-Configuration" rel="nofollow noreferrer">grouping</a> with WorkManager. We could achieve similar structure by using <a href="https://developer.android.com/reference/androidx/work/WorkContinuation" rel="nofollow noreferrer">WorkContinuation</a> but it required a reference to <a href="https://developer.android.com/reference/androidx/work/WorkRequest" rel="nofollow noreferrer">WorkRequest</a> instead of synchronizing on the same string.</p>
