background: extract-stats process is at risk of be interrupted, due to other dependent services(task-queue, es_client) may not working properly solution: 1. use begin ... rescue to handle potential exceptions - when ES and task-queue not working properly, sleep 10s and visit again - when "result_root" does not exist, skip and remove task from task-queue 2. refactor for consume_sched_queue() of stats_worker.cr
