Currently, NetworkStatsManager queries and callbacks only allow selecting network traffic based on network identifiers: networkType, subscriptionId and networkId. The code ends up converting these into a template under the hood. Now that templates can express more fine-grained queries (e.g., select only roaming traffic, or select only traffic that's not on the default network) add a hidden method to pass in a template. This should have no security implications, as all the access controls are performed in NetworkStatsService.
