kubergrunt eks verify does not work behind HTTP Proxies

[kitos9112]

Hello,

Cannot verify the EKS Cluster state behind a corporate network that presents HTTP proxy.

After v0.6.14 I can successfully retrieve the OIDC thumbprint, but not verify the cluster state. The following command sits there indefinitely waiting until the client times out. Not 100% where the issue lays in the source code though. I suspect you're using the AWS SDK for EKS in here.

❯kubergrunt eks verify --eks-cluster-arn arn:aws:eks:eu-west-1:<AccountID>:cluster/<ClusterName> --wait
