For anyone hitting this issue with AKS clusters:  I have embedded the
workaround above in a daemonset to avoid having to restart all nodes
(for now)

https://gist.github.com/skinny/96e7feb6b347299ebfacaa76295a82e7

- Please check the image+tag used in the daemonset to whatever is available in 
your cluster.
- Deploy this daemonset to the cluster (default namespace is used)
- After all pods are running 1/1 for a bit, you can delete it
- Images can be pulled again :)
