Code review comment for ~pieq/plainbox-provider-certification-client:fix1715592-touchpad-jobs

Good question. This test plan is based off the Certification Client test plan. I was actually wondering whether or not to keep these jobs and decided to leave them there (instead of deleting them completely) in order to gather more information in the final submission file that could be useful for us to investigate issues when an OEM reports problems when testing touchpads using Checkbox and this test plan.

If you think a rework is needed for this, we should do it and also "backport" these changes into the Cert Client test plan.
