Create new PowerUsageAdvanced page

This page contains the graph at the top and app list at the bottom

In this cl, we reused some part of the code in PowerUsageAdvancedLegacy
to construct the graph, and also used controller to construct the app
list(So glad that we extracted it to controller before..)
