[QE] Reportportal launch for failed pipeline run

[lilyLuLiu]

Currently, if the pipeline run failed before reportportal-import task, there is no record of the failure(as pipeline run periodically clean).
Add a post task for pipeline run if it's failed. This task will create a XML file that include the failure details and import the xml file to reportportal.

Do we have any example of this error?

[lilyLuLiu]

We aim to using reportportal to check all tests as ocp clear pipeline runs in one or two days. But if pipeline failed before task reportportal-import(like the picture), there is nothing imported into reportportal. We even don't know there is a test run failed from reportportal.

So we need a final task that triggered if the pipeline run failed. This task will collect the failed info and import to reportportal.

• To gather the failed pipeline-run logs, the task needs in the final block.
• To upload the pipeline-run logs to reportportal, the task should run before the reporportal task.
• Also, removing the folder in PVC should be executed after the reportportal task
• But in the final block, all tasks run in parallel. Can't realize get pipeline-run log first, then upload to reportportal

So I plan to upgrade the reportportal task, it will contain 4 steps in the task

1. get current pipeline logs (disabled in default)
2. transfer the log to XML file (disabled in default)
3. upload all XML files to reporportal
4. remove the pvc folder (disabled in default)

@adrianriobo WDYT?
