Add the possibility to add annotations to CRDs of Scale Set controller

[altingjonbalajj]

If you use ArgoCD to manage the Helm Chart deployment in Kubernetes there will come a point where adding the annotation of last applied resource shows an error and that is added on Client Side apply.

For this in ArgoCD an annotation is added to these resources so specific resources are applied using Server Side apply and the annotation of last applied is not defined in the resource anymore.
