 Description   

Drop-pending collections don't have an entry in the durable catalog, which SERVER-62427 is making use of to determine the collection namespace. We'll have to retrieve the collection namespace from the drop-pending collection reaper

 

System -> checkpointTimestamp = 10, oldestTimestamp = 15
Client -> Rename collection "a" to "b" at timestamp 20
System -> checkpointTimestamp = 10, oldestTimestamp = 25
Client -> Open $backupCursor. Will copy files at the checkpointTimestamp
Client -> Comes across the file for renamed collection. ns field is "b". Want "a".

We need a way to keep track of collection renames in memory.
