kaniko-builder fails because of dockerhub rate limits

[ialidzhikov]

/kind bug /priority 1

What happened: Initially kaniko builder was introduced as the solution to the ongoing issues with dockerhub rate limits across the pipelines.

Since 2 days we observe dockerhub rate limits with kaniko builder. These issues block the development and testing of various components.

error building image: GET https://index.docker.io/v2/library/golang/manifests/1.16.6: TOOMANYREQUESTS: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit
