This PR modfies the original 3-valued cron strings used in package schedule to be traditional 5-valued cron strings. - schedule.Weekly will validate that the month and dom fields are equal to * - cli autostart/autostop will attempt to detect local timezone using TZ env var, defaulting to UTC - cli autostart/autostop no longer accepts a raw schedule -- instead use the --minute, --hour, --dow, and --tz arguments. - Default schedules are provided that should suffice for most users. Fixes #993
