Support auto add karpenter.sh/unregistered:NoExecute taint on node in custom cluster-type

[kaiiyvwu]

What would you like to be added:
Support auto add karpenter.sh/unregistered:NoExecute taint on node if the cluster-type is not ACKManaged

Why is this needed:
If the cluster-type is not ACKManaged and the taint is not added on the node before node ready, the node will not be managed by Karpenter

Completion requirements:

The artifacts should be linked in subsequent comments.

I'm currently developing this controller

Based on my testing, adding the karpenter.sh/unregistered:NoExecute taint via a controller may still cause the node to be unmanaged by Karpenter. So if yout cluster-type is not ACKManaged, please set the taint by such as kubeadm join config before the node join into you cluster.
