Feature request: Minikube image load - progress bar

[stianteien]

What Happened?

When loading my local image into minikube it is often larger images that takes some time. It will amazing if I can get some kind of progress bar for the loading. I am sitting 10+ minutes wondering if there is some issues..
It is possible to see in "docker stats" under the I/O of system. But would like it in minikube command :)

Attach the log file

minikube image load "my-image"
[######-------------] 39%

Operating System

Driver

With the current API there is no means in which to provide progress, so you would have to use a docker client.

        // Load an image idempotently into the runtime on a host
        LoadImage(string) error
        // Pull an image to the runtime from the container registry
        PullImage(string) error
        // Build an image idempotently into the runtime on a host
        BuildImage(string, string, string, bool, []string, []string) error
        // Save an image from the runtime on a host
        SaveImage(string, string) error
        // Tag an image
        TagImage(string, string) error
        // Push an image from the runtime to the container registry
        PushImage(string) error

That is, first do minikube docker-env to set up the host and then do docker load to get better progress report.

If you are running an external docker daemon, you would have to juggle the environment for each one.

$ docker save python | ( eval $(minikube docker-env); docker load )

Minikube offers several ways to do faster iteration of updating images, while "save | load" is the slowest.
