Integration test for SSL verification
Following on from #7822, we need a full test of the smart proxy rack+WEBrick application to ensure that SSL verification and other auth features are working end to end.
fixes #7832 - add SSL verification tests for production Rack apps
Uses the Rack app configurations built by the smart proxy launcher with
the Sinatra authz helpers inside a WEBrick server running as part of the
integration test. Real requests are made against the server to test the
SSL configuration and helper behaviours.
