EBS CSI Driver issue causing kubetest2 failures - IMDS metadata and Kubernetes metadata are both unavailable

[mmerkes]

Which jobs are failing:

pull-cloud-provider-aws-e2e-kubetest2-quick
pull-cloud-provider-aws-e2e-kubetest2

Which test(s) are failing:
BeforeSuite is failing because CPI nodes aren't stabilizing.

Since when has it been failing:
This one passed on 10/31.

This one failed on 11/6. So sometime between these two.

Testgrid link:

1. First seen failure
2. Failed 11/25

Reason for failure:

EBS CSI pod is not stabilizing:

Not sure if they're related to each other, but also see this error in kubelet:

Not sure if they're related to each other, but also see this error in kubelet:

Very likely related - as I believe it is the AWS CCM that adds the labels we rely on for metadata to the node.

Sounds right. Looks like that's a red herring.

I'm getting this error on Openshift .... Any ideas how to solve it? Thanks.
