Kubelet: Periodically reporting image pulling progress in log

Addresses https://github.com/kubernetes/kubernetes/issues/26075#issuecomment-221129896 and https://github.com/kubernetes/kubernetes/pull/26122#issuecomment-221128397.

This PR changes kube_docker_client to log pulling progress every *10* seconds. We can't print all progress messages into the log, because there are too many. So I make it report newest progress every 10 seconds to reduce log spam.
If the image pulling is too slow or stuck, we'll see image pulling progress unchanged or changed little overtime.

The following is the result if I set the reporting interval to *1* second.
```
