> Store checkpoint meta data in checkpoint directory.  That makes it simpler for users
to track and clean up checkpoints manually, if they want to retain externalized checkpoints
across cancellations and terminal failures.
> Every state backend needs to be able to provide a storage location for the checkpoint
metadata. The memory state backend would hence not work with externalized checkpoints, unless
one sets explicitly a parameter `setExternalizedCheckpointsLocation(uri)`.
