Is there a reason why worker cron is a setting in gitlab.yml?

Good question raised here: omnibus-gitlab!1526 (comment 28600075)

Why don't we have a page in the admin section for the cron tasks?

Looking at the code, I couldn't find a good reason why this configuration is in the gitlab.yml file.

@smcgivern Do you know?
