Out of curiosity, I know there are some undocumented config parameters like

DEFAULT_AWS_CLIENT_PROVIDER

that can be added to your metaflow config. Is it expected that these configurations are not propagated to AWS Batch? Is the metaflow config file getting passed along by other means? Otherwise it seems like we'd be missing a bunch of configs here https://github.com/Netflix/metaflow/blob/master/metaflow/plugins/aws/batch/batch.py#L232-L236
