Need aws-go-sdk version updated to support iam:AssumeRoleWithWebIdentity at EKS

[hippothewild]

Hi, I've been using Escalator so far for scaling k8s clusters with Spark batch jobs running inside. Thanks for building an awesome product!

I'm currently running Kubernetes cluster with Kops+Kiam which do not have any issue about assuming IAM role for Escalator pod, but when I try to run Escalator on EKS-managed cluster, it can't assume IAM role given by service account.

The root cause is that older version of AWS SDK does not support iam:AssumeRoleWithWebIdentity with OIDC provider. it seems resolvable when we update AWS SDK to the latest version - 1.23.13 is the minimum verison required.

It will be greatly appreciated if the new version with updated SDK is released. Thank you so much!
