Bug: Upgrade failing on Kubernetes client model attribute

Expected Behaviour

Cluster is upgraded and the nodes are updated as required.

Current Behaviour

Upgrade fails after preflights and cluster upgrade in the node eviction stage.

ERROR:eksupgrade.starter:Error encountered during actual update! Exception: Unable to Delete the Node
ERROR:eksupgrade.starter:Exception encountered in main method - Error: Unable to Delete the Node
