-----------------------------------------
FYI, managed to get some assertion failures which look like the fault injection
kicking in on listings on a test with -Ds3guard -Ddynamodb

presumably listing quirks...but doesn't go away when I turn s3guard off, or on
later runs. Something isn't cleaning up

> Add a diagnostics command to s3guard which does whatever we need to diagnose
> problems for a specific (named) s3a url. This is something which can be
> attached to bug reports as well as used by developers.
> * Properties to log (with provenance attribute, which can track bucket
> overrides: s3guard metastore setup, autocreate, capacity,....
> * table present/absent
> * # of keys in DDB table for that bucket?
> * any other stats?
