Update awslabs/kubernetes-iteration-toolkit to use new 1.22+ versions

[kschumy]

https://github.com/awslabs/kubernetes-iteration-toolkit uses EKS-D as their version of K8s. They are using outdated versions and outdated versions of certain proejcts (e.g. etcd)

Hi, i would like to take a stab at this as a first issue. However i would like to have some clarifications if possible please. I can see that KIT is already using 1.23 here https://github.com/sushimaAws/kubernetes-iteration-toolkit/blob/main/operator/pkg/utils/imageprovider/imageprovider.go#L23 . So we need a way to pin etcd, coredns, AWSIamAuthenticator , AWSIamAuthenticator against certain k8s versions right ?

Hi @premdass! Thank you for your interest in this. We'd need to update their versions the latest for each of the Kubernetes versions as well as the other projects.

These lines need to be changed:

kubeVersion119Tag = "v1.19.13-eks-1-19-9"   // change to "v1.19.16-eks-1-19-22"
kubeVersion120Tag = "v1.20.7-eks-1-20-6"   // change to "v1.20.15-eks-1-20-22"
kubeVersion121Tag = "v1.21.2-eks-1-21-4"    // change to "v1.21.14-eks-1-21-20"
kubeVersion122Tag = "v1.22.6-eks-1-22-5"  // change to "v1.22.15-eks-1-22-12"
kubeVersion123Tag = "v1.23.9-eks-1-23-5"  // change to "v1.23.12-eks-1-23-7"

And for the second part, you're correct. We would need to allow for etcd, coredns, and iamAuth to return different versions based on the Kubernetes versions.

As of today, these are the versions, though they may change. The easiest way to them is to look at https://github.com/aws/eks-distro/blob/main/docs/contents/releases/1-<##>/<LATEST VERSION>/index.md

1.19
etcd: v3.4.18-eks-1-19-22

iamAuth: v0.5.9-eks-1-19-22

1.20
etcd: v3.4.21-eks-1-20-22
coredns: v1.8.3-eks-1-20-22
iamAuth: v0.5.9-eks-1-20-22

1.21
etcd: v3.4.21-eks-1-21-20
coredns: v1.8.4-eks-1-21-20
iamAuth: v0.5.9-eks-1-21-20

1.22
etcd: v3.5.4-eks-1-22-12
coredns: v1.8.7-eks-1-22-12

Do they need 1.19 and 1.20 now that both are out of support?
