Validate deletion of leaflist entry on nxos

[mahen-g]

The below format is the supported xpath to delete a leaflist entry on nxos.
Please check if we could use the below xpath to perform deletion.

/network-instances/network-instance[name=foo]/config/enabled-address-families[.=IPV4]

Thanks,
Mahendra

There is nothing I see in the infrastructure that would prevent this delete message based on the xpath from reaching the device in the proper format. Does it fail for you?

@miott This is primarily a task track on me ;) I didn't have an immediate answer on if the XPath format with .=... would be handled by the XPath regex and emitted gNMI path would be supported. This relates back to handy XPath unit tests - #70
