Add support for EKS Amazon Linux 2023 optimized AMIs
EKS nodes will deploy with the default Amazon EKS optimized Amazon Linux AMI, which is based on Amazon Linux 2. Recently Amazon Linux 2023 versions have been made available however and this is planned to be the default in EKS 1.30.
This new version comes with a different method to bootstrap the nodes to a cluster instead of the previous bootstrap userdata method based on nodeadm
. Support for this will need to be handled since GET uses launch templates by default.
