> removeOldCheckpoints in TransactionalStateTaskStorageManager currently treats every file
in the logged store base directory as if it is a directory; not always true as there is no
guarantee that the base directory has _only_ stores in it (there could be other files unrelated
to stores depending on how the user has configured the directory).
> We should only be calling listFiles on files that we know to be directories.
> Bonus points if we can search only directories we know to be stores
