Add OutOfServiceTaint to Node Instead of Deleting Node Object

[clobrano]

User Story

As an operator, I would like to add an OutOfServiceTaint to a Node instead of deleting the Node object.

• use core functionality to obtain the same goal is a cleaner approach
• no need to backup and restore the Node

Detailed Description

For Kubernetes >= 1.28 Add the out-of-service taint in place of deleting the Node object Kubernetes >= 1.28

For Kubernetes < 1.28 Keep the current behavior

Anything else you would like to add:
