This CL introduces cellular data stall recovery based on network validation result. It still re-uses the existing recovery steps but the triggers are based on networkStatus from NetworkMonitor when the network is bad. Each recovery step is spaced by a configurable grace period (default 3 mins) to avoid back to back recovery. This feature is controlled by the following settings. If this feature is enabled then the legacy data stall detection based on TrafficStats will automatically be disabled. Settings.Global.DATA_STALL_RECOVERY_ON_BAD_NETWORK 1 => Enabled (default) 0 => Disabled Settings.Global.MIN_DURATION_BETWEEN_RECOVERY_STEPS_IN_MS 3 minutes is default value Bug: 113916551 Test: atest FrameworksTelephonyTests:com.android.internal.telephony.dataconnection.DcTrackerTest Change-Id: I738fc7ed08803de1114f7a3d79bf278449e94ea8
