CRD embedded ObjectMeta preservation during version conversion

[champak]

I ran into an issue with converting CRDs between versions with kubebuilder 2.2.0. This CRD has embedded native types in the spec like services, pods etc. First I got complaints about "preserveUnknownFields" : spec.conversion.strategy: Invalid value: "Webhook": must be None if spec.preserveUnknownFields is true. I got around that with setting "preserveUnknownFields" to false in the webhook patch that enables the conversion webhook. With the workaround I can get deployed but find that when I am converting in the <>ConvertTo functions the ObjectMeta info for the native objects embedded in my CRD spec are MIA ! The ObjectMeta info for the CRD itself shows up OK. I suspect preserveUnknownFields=false somehow gets in the way of the ObjectMeta info getting propagated correctly. Attributes other than the ObjectMeta info seem to show up OK.

The controller-tools are at v0.2.4; I could not locate an issue that describes this exact issue on either controller-tools or this repo. Thanks for any insights, workarounds !
