stress_ng_test.py should provide the exact command for what it runs #1713
Description
Enhancement Proposal
often when debugging a failure we want to rerun a single stressor that has failed, but run it the same way that checkbox ran it during the test run. That usually means some digging into the code to piece the command together that was run by hand.
Instead, each stressor should dump the command being run when it is initiated, so that the output contains an easy to find clue to how to reproduce that particular stressor job.
