> Today, the global AM max-attempts is set to 1 which is a bad choice. AM max-attempts
accounts for both AM level failures as well as container crashes due to localization issue,
lost nodes etc. To account for AM crashes due to problems that are not caused by user code,
mainly lost nodes, we want to give AMs some retires.
> I propose we change it to atleast two. Can change it to 4 to match other retry-configs.
