[C++] S3 stress tests can fail to delete a temporary directory

[bkietz]

Describe the enhancement requested

This seems to be causing spurious failures of the stress test, for example:

I'm not sure this is actually the issue; other tests can still pass even if deletion of a temporary directory succeeds:

I suppose this is only on Windows? Constraints on file deletion on Windows are annoying...

Is the file deletion relevant to the test? Maybe we could "fix" it by just not deleting on Windows (maybe logging paths of files in case someone needs to delete them by hand)

I would suggest retrying the DeleteDirContents call a number of times, with sleeps in between.
