Cron jobs allow you to submit build manifests at a scheduled interval. Cron jobs can either be configured to run
monthly. When a cron job is scheduled it will always trigger at the start of it's schedule, so a
daily cron job will run at the start of the next day,
weekly would be the start of the next week, and
monthly would be the start of the next month.
Crons can either be standalone, or grouped into a namespace. Crons are grouped into a namespace by specifying the
namespace field in the build manifest you want to use for that cron.
