描述

I've recently started making use of the minikube image cache. When starting minikube, the startup stalls for a very long time at the following:

😄  minikube v1.8.2 on Linuxmint 19.3
✨  Using the kvm2 driver based on user configuration
🔥  Creating kvm2 VM (CPUs=8, Memory=18432MB, Disk=40000MB) ...
🐳  Preparing Kubernetes v1.17.3 on Docker 19.03.6 ...
🚀  Launching Kubernetes ... 
🌟  Enabling addons: default-storageclass, storage-provisioner

The first few times I encountered this, I though something had broken. It would be helpful to indicate to the user that progress is being made.

研究方向
Start by examining the minikube startup flow in the `cmd/minikube/cmd/start.go` file. The image cache transfer likely occurs in the `pkg/minikube/machine` or `pkg/minikube/cache` directories. Look for functions that handle transferring cached images from host to VM. Consider using a progress bar library like `github.com/cheggaaa/pb` or the built in `spinner` package used elsewhere. Review existing progress bar implementations in the codebase for patterns, such as in `pkg/minikube/constants/progress.go`. The issue is open and no one has submitted a PR, so it's available for contribution.
