daysToBuild: ScheduleDays. Days for a build (flags enum for days of the week)
scheduleJobId: string. The Job ID of the Scheduled job that will queue the scheduled build. Since a single trigger can have multiple schedules and we want a single job to process a single schedule (since each schedule has a list of branches to build), the schedule itself needs to define the Job Id. This value will be filled in when a definition is added or updated. The UI does not provide it or use it.
startHours: number. Local timezone hour to start
startMinutes: number. Local timezone minute to start
timeZoneId: string. Time zone of the build schedule (string representation of the time zone id)
