      Description

      Currently on app attempt page we can see outstanding resource requests, it will be helpful for users to know why if we can join diagnostics of this app with these. 

      Discussed with Weiwei Yang, we can passively load diagnostics from cache of completed app activities instead of actively triggering which may bring uncontrollable risks.

      For example:

      (1) At first we can see no diagnostic in cache if app activities not triggered below the outstanding requests.

      (2) After requesting the application activities REST API, we can see diagnostics now.
