applyconfiguration-gen generates incorrect Extract...Status()

[Gchbg]

This has tested with 0.29.4, 0.30.0, and the current master branch.

applyconfiguration-gen generates (experimental!) ExtractXYZ() and ExtractXYZStatus() functions that take an object and deliver an applyconfiguration that only has those fields prefilled that are owned by a given field manager.

The ExtractXYZStatus() does not extract conditions correctly. In the status of our CRD we have standard Kubernetes conditions:

	// +patchStrategy=merge
	// +patchMergeKey=type
	// +optional
	Conditions []metav1.Condition `json:"conditions,omitempty" patchStrategy:"merge" patchMergeKey:"type" protobuf:"bytes,1,rep,name=conditions"`

In an object that has one condition set by a controller using SSA, a subsequent reconcile by the same controller (using the same field manager value in both cases) calls ExtractXYZStatus(), which extracts all other owned fields correctly, but the Conditions slice is always nil in the output applyconfiguration. This has the effect that every time the controller wants to set any other field in the status, it inadvertantly clears its own conditions.

Instead I would expect that the applyconfiguration contains the condition previously set by the same controller.
