Add an automatic storage management job service. 

This service runs once a day when plugged in when the device has
under 15% free space remaining. If the FeatureFactory has a
storage management job, it runs the job to begin to free up space
on the device.

This is a temporary landing place and will be refactored very
quickly out of Settings.
