Test image registry connectivity should also ignore scheme prefixed proxy

minikube/pkg/minikube/node/start.go

Lines 498 to 501 in b1ccf54

	proxy := os.Getenv("HTTPS_PROXY")
	if proxy != "" && !strings.HasPrefix(proxy, "localhost") && !strings.HasPrefix(proxy, "127.0") {
	opts = append([]string{"-x", proxy}, opts...)
	}

Could extract a util function from #8885

By the way, I am wondering if we can convert localhost to host machine IP? Or add a flag to replace localhost?

something like: minikube start --host-ip=$(nmcli -g ip4.address dev show eth0)

I believe you can set the DOCKER_HOST environment variable and we will honor that IP address instead of localhost.
