 // Launches the app at startup. The flow roughly looks like this:
 // First call Initialize():
 // - Attempts to load oauth token file. Stores the loaded tokens in
 //   |auth_params_|.
 // - Initialize token service and inject |auth_params_| if needed.
 // - Initialize network if app is not installed or not offline_enabled.
 // - If network is online, install or update the app as needed.
 // - After the app is installed/updated, launch it and finish the flow;
 // Report OnLauncherInitialized() or OnLaunchFailed() to observers:
 // - If all goes good, launches the app and finish the flow;
