eks: Add support for Node Health Monitoring and Repair

[dwickr]

Describe the feature

The Node Health Monitoring and Repair feature was recently announced. It "monitors the health of the EC2 instances (nodes) in EKS clusters for Kubernetes-specific health issues and automatically takes action to repair them if they become unhealthy."

Use Case

I want to monitor the health of instances in my NodeGroups beyond the existing EC2 Health Check the ASG uses.

Proposed Solution

Hi @dwickr , thanks for requesting this. I see that cloduformation supports this - https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-eks-nodegroup-noderepairconfig.html and we also have this updated and supported in L1 construct -https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_eks.CfnNodegroup.NodeRepairConfigProperty.html , hence CDK support is feasible.

Marking this as P2 which means contribution from the community are welcome as well as from the team.
