providers/base/bin/stress-ng-test.py Provide the exact command executed for each stressor (New)

[bladernr]

Provide the exact command executed for each stressor or set of stressors. Fixes CHECKBOX-1734

Description

Short addition to provide the exact command checkbox runs for a given stressor or set of stressors in the stress-ng tests to make it easier to later re-run a single stressor by hand when investigating failures.

Resolved issues

Resolves CHECKBOX-1734
Resolves #1713

Documentation

No docs changes needed.

Tests

Executed cpu, disk and memory stress tests locally (using very abbreviated runtimes) to confirm that the commands were provided for each test case. In the case of the disk and memory tests, which run them individually, output looks like this:

$ sudo ./stress_ng_test.py disk -d /dev/sdc -b 1
Using test directory: '/mnt/sdc/tmp/stress-ng-33748cb3-e56f-11ef-a0bc-d8bbc1046e12'
