Bug 443809 - Move work in AutomaticUpdateScheduler to a JobI20200428-0630I20200428-0610

Move the work from the earlyStartup to a Job. This reduces the execution
time of the the early startup workload from 1344ms to 52ms.
Also delays the update check to allow the system to settle before the
update check
