> We have a default value 100 for Rolling Upgrade batch size. In order to
> modify that size, upgrade.xml should have <max-degree-of-parallelism> or
> stack should define it.
> However, we can provide a way to update the batch size dynamically using some
> config that can be updated by client using Rest API and subsequent Rolling
> Upgrade can get the updated batch size from the config.
