[feature request]improve FieldIndexer setting in yurt-manager

[rambohe-ch]

What would you like to be added:
In NodeLifeCycle and PodBinding controller of yurt-manager component, spec.nodeName IndexField has been used at present, and FieldIndexer setting is only needed to configured only once, and now is configured in NodeLifeCycle controller as following:

openyurt/pkg/yurtmanager/controller/nodelifecycle/node_lifecycle_controller.go

Lines 332 to 344 in 3636ec0

	if err := mgr.GetFieldIndexer().IndexField(context.TODO(), &v1.Pod{}, nodeNameKeyIndex, func(rawObj client.Object) []string {
	pod, ok := rawObj.(*v1.Pod)
	if !ok {
	return []string{}
	}
	if len(pod.Spec.NodeName) == 0 {
	return []string{}
	}
	return []string{pod.Spec.NodeName}
	}); err != nil {
	klog.Errorf("could not register spec.NodeName field indexers for nodelifecycle controller, %v", err)
	return err
	}

This FieldIndexer setting is shared by two controllers, maybe it is a good idea to move this sharing setting as a public setting instead of configuring in NodeLifeCycle controller.

Because in some scenarios, users like to disable NodeLifeCycle controller, so FieldIndexer setting will not be configured, then an error happens in PodBinding controller as following:

E1113 13:40:14.428554       1 podbinding_controller.go:180] pod-binding-controller: failed to get podList for node(izbp13108hhdvq7ver655tz), Index with name field:spec.nodeName does not exist
E1113 13:40:14.428590       1 controller.go:317] setup/controller/pod-binding-controller "msg"="Reconciler error" "error"="Index with name field:spec.nodeName does not exist" "name"="izbp13108hhdvq7ver655tz" "namespace"=""
