Hi there!

The label control-plane: controller-manager is the default from Kubebuilder scaffolding, but it's too generic.
In environments with multiple custom controllers, this label may unintentionally match unrelated Pods or Services, leading to incorrect selection or monitoring.

This PR updates it to control-plane: kruise-controller-manager to make it specific to Kruise and avoid such conflicts.

Thanks!
