How do you configure options for Multus like Namespace Isolation

[evilhamsterman]

According to this document https://github.com/k8snetworkplumbingwg/multus-cni/blob/master/docs/configuration.md#Namespace-Isolation it looks like you can enable various features on Multus such as Namespace Isolation to limit access to certain networks to specific namespaces.

However I cannot figure out where I add this value. Does it get added to the multus-daemon-config configmap? That doesn't seem to match the file in /etc/cni/net.d/00-multus.conf which appears to be generated. Do you have to add it to every NetworkAttachmentDefinition?
