@StephanEwen Do you have time to look at this? This exposes the checkpoint
directories via the state backend and let's the JobManager use that one for
checkpoint directory configurations.
> Remove extra storage location for externalized checkpoint metadata

> 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)`.
