> Jenkins can do automatic load balancing for cron jobs that use the "H" syntax
> [1], but we apply it only sporadically (and often incorrectly) in Beam. For
> example, the default setting is currently '0 */6 * * *' [2]. This means
> "every six hours, starting from exactly 00:00 (UTC)." Which creates load
> spikes every 6 hours, since a ton of jobs are run at once, rather than being
> staggered.
