The s3api cross-compat tests in test_service weren't sophisticated
enough to account for real s3 session credentials that could see actual
aws s3 buckets (or a vsaio you actually use) - however valid assertions
on the authorization logic doesn't actually require such a strictly
clean slate.
Drive-by: prefer test config option without double negative, and update
ansible that's based on the sample config.
