Mirror prebuilt Docker image to ECR Public

[sorah]

What would you like to be added: Have a image available on ECR Public

Why is this needed: To avoid rate limit against DockerHub

Related to #5, do you have a plan to publish Docker images currently only available on DockerHub to ECR Public? It would be convenient to avoid rate limit error from DockerHub.

Any chance for traction on this issue? This would be a huge improvement

Id even entertain publishing under ghcr.io if thats acceptable to get around rate limits. ECR public would be the best, but happy to pr the build action here to support a ghcr.io target.

@nckturner @emattiza looks like we can pick up this workflow from aws-ebs-csi-driver:
https://github.com/kubernetes-sigs/aws-ebs-csi-driver/blob/master/.github/workflows/publish-ecr.yaml

and adapt it for us here?

[emattiza]

I agree @dims, and there are some makefile tweaks and a ./hack/provenance buildx test script. Happy to be the code mover if someone can handle the secret provisioning that will be support the PR.

@emattiza please give it a shot! yea, i think we should be able to do the secret stuff
