CA: Updating AWS-SDK-Go to 1.26.6

[gjtempleton]

This brings in the new EC2 DescribeInstanceTypes API.

Also updates the AWS-Manager test for Region fetching due to changes in the SDK in how this is done due to aws/aws-sdk-go#2969

Updating vendor against git@github.com:kubernetes/kubernetes.git:711790af23a231ade04c6c39d6bc5dcf1a996f73 (711790a)

Broken out from the changes to the EC2 instance type list enabled by this SDK update to simplify reviewing of the PRs.

Related to #2696

Thanks! Seems this is a prerequisite for the next step. Let's merge this dependency update separately. Looks good to me

/lgtm

/hold

I've just had a look again and am seeing more changes than I expected, particularly in vendored files under a k8s.io path.

Looks like these reversions are all reversions of changes brought in by #2605 . They seem unrelated to the changes intended by that PR, but could you please confirm @jaypipes just to be certain.

@gjtempleton nope, these changes are all good. This PR is adding the new aws-sdk-go 1.26.6 package to the cluster-autoscaler/vendor/github.com/aws/aws-sdk-go directory. This is proper, as the hack/update-vendor.sh script runs go mod vendor after replacing the packages listed in go-mod.extra in the go.mod file generated from upstream k/k. #2605 replaced the "sub-vendored" cluster-autoscaler/cloudprovider/digitalocean/godo package with cluster-autoscaler/vendor/github.com/digitalocean/godo.

In short, we're all good here :)

[gjtempleton]

Brilliant, thanks for the confirmation!

Closing as this is made redundant by the merging of #2796

Will port across the code fix for the failing test mentioned in #2797 to a separate PR
