PackageVariant debugging from Nephio

[johnbelamaric]

This commit adds a workaround for an issue with Kptfile rendering that is causing a controller battle between PackageVariant controller and the Nephio controllers.

It also adds some instrumentation to help debug some issues with PackageVariant cloning.

e2e flaked out. Definitely see occasional issues with the packagerev finalizers, which then causes timeouts. I wonder if it is the test git server failing somehow.

This looks good to me.

I asked chatgpt to help :) and it generated the following.

package main

import (
	"fmt"
	"reflect"

	"k8s.io/apimachinery/pkg/apis/meta/v1/unstructured"
	"k8s.io/apimachinery/pkg/util/yaml"
)

func main() {
	// Example YAML strings
	yamlString1 := `
apiVersion: v1
kind: Pod
metadata:
  name: pod-1
spec:
  containers:
  - name: container-1
    image: nginx:latest
  - name: container-2
    image: redis:latest
`
	yamlString2 := `
apiVersion: v1
kind: Pod
metadata:
  name: pod-2
spec:
  containers:
  - name: container-1
    image: nginx:latest
  - name: container-2
    image: redis:latest
`

	// Convert YAML strings to unstructured objects
	obj1, err := yaml.ToUnstructured([]byte(yamlString1))
	if err != nil {
		panic(err)
	}

	obj2, err := yaml.ToUnstructured([]byte(yamlString2))
	if err != nil {
		panic(err)
	}

	// Compare unstructured objects
	equal := reflect.DeepEqual(obj1, obj2)
	fmt.Println("Objects are equal:", equal)
}
