First pass at detailed app data usage, policy.
Fragment to show application data usage details, including chart with inspection ranges. Button that invokes ACTION_MANAGE_NETWORK_USAGE towards application, and UID-specific policy controls. Fragment is launched when clicking list items from data usage summary page. Change-Id: Ie1564aa8af98e1a7083817a997059a5a7b1caa50
