What feature/behavior/change do you want?

Add the ability to set the maximum instance lifetime of instances in node groups:

https://docs.aws.amazon.com/autoscaling/ec2/userguide/asg-max-instance-lifetime.html

Why do you want this feature?

We'd like to ensure that our instances don't hang around for too long and so this would be a nice feature to have.

What would you like to be added:
Cilium is our default CNI solution on EKS-A clusters. It would be beneficial to enable Cilium metrics so that existing Prometheus could be configured to scrape those targets.

NTH Queue-Processor should catch the ASG Launch Lifecycle Hook and complete it once the node has joined the k8s cluster successfully. Since ASG considers the instance ready when EC2 health checks pass rather than when it actually joins the k8s cluster, if ASG performs Launch-Before-Terminate, a node could be terminated before the new node is ready to go.

k8s_taints are not documented right now.
see https://github.com/aws-samples/aws-eks-accelerator-for-terraform/blob/main/modules/aws-eks-managed-node-groups/locals.tf#L24

Here is a working example you can use:

k8s_taints = [{key= "purpose", value="execution", "effect"="NO_SCHEDULE"}]

I haven't tested it with fargate profiles:

Some log entries are using V(1) but still get emitted by default.
We should have a way to mute debug logs using a flag.
