Use data plans for better job scheduling. 

Now that we have data plan information from the carrier, we can start
using it to influence when we schedule jobs.  As a first pass
algorithm:

-- If the network is congested, and a job is less than 50% through
its runnable window, then we'll defer it for awhile.
-- If the network has a surplus of data, we'll consider using some
of it to improve the user experience by running prefetching jobs.

Provider APIs for carrier apps to override their connections to be
temporarily marked as either "unmetered" or "congested", along with
automatic timeouts if desired.

Flag for developers to indicate which jobs will have a material
positive impact on end users.  (We don't want to promote jobs that
are simply doing logs upload; for example.)  Glue code to quickly
return targetSdk of a specific package.

More tweaking to the exact algorithms will come in future CLs.
