Add a new API to fetch reasons why a job may be pending.
This new API (getPendingJobReasons()) is similar to the existing
getPendingJobReason API (deprecated in this change) but it returns
all potential reasons why a job may be pending rather just one
pseudo-random reason.
Also add a new pending job reason for when the override deadline
constraint is set by the app.
