Update the battery broadcast receiver.
Add a type for battery receiver, then in callback client know for
which reason it been invoked:
1. battery level change
2. battery saver state change
3. battery plug state change
So in this CL, we won't update battery tip for battery level change,
then battery tip won't be dismissed by itself.
Also note in onResume() we will manually update battery tip. So if
user stay in battery settings page and close the screen, once he opens
it we will still force update everything.
