idea: keep kubespray color

[yankay]

The KubeSpray output is colorful.

. But the kubectl logs lost the color. So there is the idea.

The color is a little useful but may have side effects. So I think it's "nice to have" and not "required".

I will look into it.

This method can highlight the log, but it cannot restore the original effect of the ansible log:
