Comment 3 for bug 1625244

Not all conditions from Expected result are satisfied:
item 2: all tasks related to the `echo to file` should be moved from tasks.yaml to the deployment_tasks.yaml.
item 3: test passed

Tasks weren't moved to the deployment tasks yaml file and that's why test [1] failed with:
FAIL: Deploy cluster with one controller and example plugin v3
