container cleanup fails to remove containers and prune etcd sometimes

[tnozicka]

If the issue is the clean up that shouldn't make the job fail.

No, please look at jUnit output:

Cleanup is best-effort and cannot fail a job.

[tnozicka]

@stevekuznetsov seems like I was wrong in the cause although the cleanup seem broken:

Error response from daemon: You cannot remove a running container

Why not use -f there?

This seems wrong as well:

rm: cannot remove ‘/tmp/etcd/openshift-backup-etcd_backup_tag20170824115222’: Permission denied
rm: cannot remove ‘/tmp/etcd/openshift-backup-etcd_backup_tag20170824115200’: Permission denied
rm: cannot remove ‘/tmp/etcd/member’: Permission denied

[stevekuznetsov]

I mean, yes, the cleanup is failing, but it doesn't matter. if you'd like to clean it up, you may, but it is not impacting any workflows today.
