When the app contains anomaly, we should show anomaly icon(triangle
alert).
This cl also extracts a new method refreshAppListGroup from refreshUi.
New method is used to only refresh appListGroup. Reason for this action:
1. Improve performance(partial refresh)
2. We init AnomalyLoader in refreshUi, invoke refreshUi in
onLoadFinish will create infinite loop.
