Will this script warn anywhere if there are no matching checkpoints here?

It will say (as an info log, line 817) there are no matching directories and then will exit gracefully. There will be ~10 lines of logs from the whole program in this scenario, so it won't be a needle in a haystack.

This is the first of a few PRs with refactored versions of changes I have been using locally for checkpoint management. This PR focusses on my changes to the storage cleaner's unsharding functionality:
TrainConfig. This has been done in a hacky way (passing an emptyTrainConfigto the checkpointer), relying on the fact that unsharding doesn't use the config at all.
