With `aws-sdk-go-v2@1.24.1`, API server requests containing URLs presigned by `sts.PresignClient` fail with an `Unauthorized` error. `aws-sdk-go-v2@1.24.1` adds an extra header `amz-sdk-request` to the generated request, but this header is not allow-listed by `aws-iam-authenticator` server running on the control plane. This is likely due to [this change](aws/aws-sdk-go-v2#2438) which reorders the middleware operations to execute `RetryMetricsHeader` before `Signing`. This changelist removes the `RetryMetricsHeader` middleware from the stack when constructing `sts.PresignClient`.
