Remove seqNo and priTerm from Job HistoryModel

[cwperks]

Description

Re-opening #822, but isolating the changes to just the newly introduced HistoryModel.

This PR removes manual tracking of seqNo and priTerm for the StatusHistoryModel. See details here about why they make sense on the LockModel. Since an entry in job history is recorded after successful acquisition of a Lock, we can be assured at that point in time that multiple nodes would not be trying to record simultaneously, only the node that successfully acquires a lock will. These fields serve no real purpose and can be safely removed.
