* Don't test tunnels expiring within 90 seconds * Defer Test Tunnel jobs if job lag too large * Use JobQueue.getMaxLag() rather than the jobQueue.jobLag stat to measure job lag for tunnel build backoff, allowing for more agile handling (since the stat is only updated once a minute) * Use tunnel length override if all tunnels are expiring within one minute.
