CronJobs should support timeZone field instead of CRON_TZ

[matthewmrichter]

The Kubernetes cronJob spec does not support the CRON_TZ=xxx * * * * * format for crons and never did: https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/#cron-job-limitations

Error: UPGRADE FAILED: an error occurred while rolling back the release. original upgrade error: cannot patch "hello-world-cron-1" with kind CronJob: CronJob.batch "hello-world-cron-1" is invalid: spec.schedule: Invalid value: "CRON_TZ=Etc/UTC */20 * * * *": cannot use TZ or CRON_TZ in schedule, use timeZone field instead 

Desired:

• cronJobs.[name].timeZone parameter
• cronJobsGeneral.timeZone parameter
