Background

When creating backup schedules in AdminUI, the interface was limited to specifying a single day of the week. Ranges, among other forms, were not allowed. This also broke AdminUI when existing backup schedules created using confd_client jobs existed.

Improvement

All crontab expressions are allowed, except for nickname extensions (@daily, @weekly, etc.). The source for the allowed expressions can be read in https://linux.die.net/man/5/crontab.
