Modify the MediaWiki History Scala code to support the concept of Temp Account.
- Parse the user_is_temp field from MediaWiki's user table, and represent it across all corresponding data elements as isTemporary (and its counterpart isPermanent).
- Make sure the addition of the fields does not alter the computations: UserHistory, DenormalizedHistory, etc. Vet the output data.
- Update the Checkers to include checks or filters on isTemporary and isPermanent.
- Should this task include the MediaWiki History Reduced pipeline?
