@PascalBourdier Thanks for trying to help with these updates, it's appreciated. I closed this PR, since I released the ansible-operator-plugin and need to update/release operator-sdk with these changes.

Just any FYI, everything in /testdata is scaffold-ed content, mainly coming from kubebuilder, with some additional things layered on, so typically those files aren't/can't be edited directly.
