 Description   

WT-5927 made checkpoint cursors work again. In SERVER-63218, we implemented an in-memory historical ident tracker used to report the namespace of collections and their indexes at the time of the backup, rather than the latest known namespace.

Using checkpoint cursors, we can open the durable catalog at the time of the backup to retrieve the namespace.
