 Normally, updating a service will only cause the service's tasks to be replaced with new ones if a change to the
 service requires recreating the tasks for it to take effect. For example, only changing the
 `--update-parallelism` setting will not recreate the tasks, because the individual tasks are not affected by this
 setting. However, the `--force` flag will cause the tasks to be recreated anyway. This can be used to perform a
 rolling restart without any changes to the service parameters.
