 Description   

Passing --queryableBackupMode results in WTKVEngine to open WT with read_only=true. For queryable restores from filesystem backups in 4.2+, WT will need to be able to perform recovery.

Removing this flag will require the custom FS also defines the necessary function points.

Doing this work will require investigating which remaining methods to implement are non-trivial, which may require a separate ticket.
