how to set pod-metadata

[jbehling]

Description I'm struggling to find a way to set the metadata for a closure as in this example: https://github.com/argoproj/argo/blob/master/examples/pod-metadata.yaml. It appears that metadata isn't a valid field for any of the union types that closure supports. Is there something that I'm missing?

no the issue I'm having is that there's no way to set the metadata attribute of the template object, at the time i opened the issue it appeared that this was due to some issue in the openapi spec
