Description of your changes:

As described in #10917, exit handlers were implemented as dependent tasks that always ran within an Argo Workflow. The issue is that this caused the pipeline to have a succeeded status regardless of if the tasks within the exit handlers all succeeded.

This commit changes exit handlers to be exit lifecycle hooks on an Argo Workflow so that the overall pipeline status is not impacted.

Resolves:
#11405

Hi @mprahl. Thanks for your PR.

I'm waiting for a kubeflow member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
