> Race condition in LocalizerRunner causes container localization timeout.
> Currently LocalizerRunner will kill the ContainerLocalizer when pending list for LocalizerResourceRequestEvent
is empty.
> {code}
>       } else if (pending.isEmpty()) {
>         action = LocalizerAction.DIE;
>       }
> {code}
> If a LocalizerResourceRequestEvent is added after LocalizerRunner kill the ContainerLocalizer
due to empty pending list, this LocalizerResourceRequestEvent will never be handled.
> Without ContainerLocalizer, LocalizerRunner#update will never be called.
> The container will stay at LOCALIZING state, until the container is killed by AM due
to TASK_TIMEOUT.
