istioctl analyze regression: List type not supported

[howardjohn]

skipping unknown yaml chunk config.yaml: failed finding schema for group/version/kind: /v1/List is reported for List types. These used to be handled. I think this broke in the pilot-to-galley change.

A workaround for users is to pass through https://github.com/howardjohn/kubectl-grep, but of course that should not be required
