3b21a9901b Support terminal resizing for exec/attach/run 
Add support for terminal resizing for exec, attach, and run. Note that for Docker, exec sessions
inherit the environment from the primary process, so if the container was created with tty=false,
that means the exec session's TERM variable will default to "dumb". Users can override this by
setting TERM=xterm (or whatever is appropriate) to get the correct "smart" terminal behavior.

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.
```

Automatic merge from submit-queue

Fix PullImage and add corresponding node e2e test

Fixes #24101. This is a bug introduced by #23506, since ref #23563.

The root cause of #24101 is described [here](https://github.com/kubernetes/kubernetes/issues/24101#issuecomment-208547623).

This PR
1) Fixes #24101 by decoding the messages returned during pulling image, and return error if any of the messages contains error.
2) Add the node e2e test to detect this kind of failure.
3) Get present check out of `ConformanceImage.Remove()` and `ConformanceImage.Pull()`. Because sometimes we may expect error to occur in `PullImage()` and `RemoveImage()`, but even that doesn't happen, the `Present()` check will still return error and let the test pass.

Also /cc @resouer, because he is doing the image related functions refactoring.
