k8s-merge-robot d93f80c86b Merge pull request #26677 from Random-Liu/add-image-pull-timeout 
Automatic merge from submit-queue

Add timeout for image pulling

Fix #26300.

With this PR, if image pulling makes no progress for *1 minute*, the operation will be cancelled. Docker reports progress for every 512kB block (See [here](3d13fddd2b/pkg/progress/progressreader.go (L32))), *512kB/min* means the throughput is *<= 8.5kB/s*, which should be kind of abnormal?

It's a little hard to write unit test for this, so I just manually tested it. If I set the `defaultImagePullingStuckTimeout` to 0s, and `defaultImagePullingProgressReportInterval` to 1s, image pulling will be cancelled.
```
