[Bug] Can't create cluster in aws-cn (no versions available for "metrics-server")

[artem-nefedov]

What were you trying to accomplish?

Create cluster in AWS China.

What happened?

Cluster creation fails at addon creation with no versions available for "metrics-server", despite addon configuration not including "metrics-server" addon.

How to reproduce it?

Create cluster in AWS China (cn-north-1) with the following addon configuration:

addons:
- name: vpc-cni
  attachPolicyARNs:
    - arn:aws-cn:iam::aws:policy/AmazonEKS_CNI_Policy
  version: latest
- name: coredns
  version: latest
- name: kube-proxy
  version: latest

Anything else we need to know?

My guess is that "metrics-server" addon not available in China, but the problem is still on eksctl side since I didn't specify this addon to be deployed.
eksctl should not request version for addons that are not used.

Versions
