> Follow up for FLINK-4512.
> 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)`.
