The CWL OOM retry feature is confusing for a couple of reasons:

• It shows up as a warning, suggesting something is wrong, when nothing is wrong
• You have both a failed step and a successful step, but people see the failed step and think there's a problem.

It should:

• Not log it as a warning, and/or we should stop giving special treatment to warnings in Workbench
• Delete the failed container request so the user doesn't see a failed request in the list even when the workflow actually succeeded.
