Feature request: Time zone support for CronJobs

[sjerdo]

Currently, CronJob schedule expressions are all considered to be UTC, except for in-pod cron jobs which follow the timezone of the service

For one of our projects, we'd like to run a specific cron just after midnight (local time). But we cannot configure that, since this expression does not considers daylight saving time. 0 23 * * * will run at 00:00 AM CET or 01:00 CEST.

Timezones:
The default timezone for cron jobs is UTC.
Native cron jobs use the timezone of the node, which is UTC.
In-pod cron jobs use the timezone of the defined service, which can be configured to something other than UTC.

Kubernetes supports CronJob syntax with timezone support since v1.27: https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/#time-zones

Can you support specifying a time zone for CronJobs in .lagoon.yml ?

The only problem is that if the timezone is set, and the frequency means it lands as an in-pod cronjob, we won't do anything with the timezone. We can document this as a caveat though. The addition of the field seems simple enough though, will see what the rest of the team thinks.
