 Description   

Add a query flag that tells the query system to simply ignore oplog visibility even for forward cursors, for internal use. This is useful especially for TransactionHistoryIterator where we want to be able to see everything immediately.

Agreed, this flag isn't needed at this time.

I think we can safely close this ticket as "Won't fix". I don't think there is any issue in production code and SERVER-42925 will fix the unit test instead. Thanks.

Putting into Investigating. The query team plans to talk with the repl team in order to understand why this flag is needed.
