[Feature] Amazon Machine Images with Amazon Linux 2023 should be supported

[volphy]

What feature/behavior/change do you want?

It would be great if eksctl fully supported AMIs with Amazon Linux 2023 to build node groups and managed node groups.

At the moment of writing they are not supported:
https://eksctl.io/usage/schema/

Why do you want this feature?

Amazon Linux 2023 is the successor of Amazon Linux 2. It is more and more commonly used in the AWS public cloud.

EKS support for Amazon Linux 2023 has been recently announced:

Just a quick thought, perhaps eksctl can managed (populate automatically) the ClusterDetails and expose ContainerdOptions, InstanceOptions, KubeletOptions, LocalStorageOptions, LocalStorageStrategy for user to specify in eksctl ClusterConfig spec, then finally render the complete NodeConfig spec to the user data. API spec is here.

This could mean the once deprecated custom bootstrap script may come back alive :D

Just merged initial support for AL2023 ☝🏻. We should be able to do a RC tomorrow. Stay tuned!

@tanvp112 - that's an interesting proposition. Although it won't be part of the initial release, please feel free to open a separate feature request and we'll evaluate it.
