These are analagous to the state buckets for tracking whether usage is incurred while the app is in the foreground or background. We will additionally track whether data usage is incurred over a metered or unmetered network, and whether it is incurred over a roaming or native network. The APIs are not implemented in this CL; the existing buckets are still returned with METERING_ALL and ROAMING_ALL to indicate that this is not yet being tracked.
