This PR is extremly usefull when debugging issues with S3 backend against radosgw, so I would love to see this merged.

The only thing I'd suggest is that you squash those two commits together. They make no sense being two different commits, and as the tests fail with only the first commit will cause problems when running a git bisect.

@vleurgat do you wanna rebase?

Hi folks,
Since there's been no movement on the author's part I took the liberty to recreate this PR (with a few changes): #4076
