(aws-eks): Make sure kubectl is compatible with the k8s version

See original GitHub issue

Currently, to update Kubernetes resources, we use kubectl version 1.20, hardcoded in a lambda layer. For now, this works fine, but eventually, as new Kubernetes versions are released, they won’t be compatible with the client anymore. Also, it’s not an option to always use the latest version of the client, as we know that kubectl version 1.21.0 is not compatible with version 1.20 (and lower) of the server.

Really seems crazy there’s nothing on the roadmap for this yet.

Is there a status update on this? Any reason why there can’t be a different layer version per EKS version? AWS only supports a given EKS version for 16 months. 1.20 is end of support in approximately 3 months. Due to the rolling nature of EKS, CDK needs to support matching versions for kubectl. Once 1.20 is EOS, the control plane will automatically migrate to the next supported version breaking the use of kubectl either way.
