This PR addresses a possible failure when Redis pod was inaccessible from Crawler pod. - Ensure crawl is set to 'waiting_for_capacity' if either no crawler pods are available or no redis pod. previously, missing/inaccessible redis would not result in 'waiting_for_capacity' if crawler pods are available - Rework logic: if no crawler and redis after >60 seconds, shutdown redis. if crawler and no redis, init (or reinit) redis - track 'lastUpdatedTime' in db when incrementing exec time to avoid double counting if lastUpdatedTime has not changed, eg. if operator sync fails. - add redis timeout of 20 seconds to avoid timing out operator responses if redis conn takes too long, assume unavailable
