Implements the minikube image save command:

minikube --alsologtostderr image load --pull busybox

minikube --alsologtostderr image save busybox busybox.tar

It looks big because of the somewhat silly structure of "machine", and the missing CopyFrom functionality for VM "assets":

NewFileAsset: busybox.tar -> /var/lib/minikube/images/busybox.tar

scp /var/lib/minikube/images/busybox.tar --> busybox.tar (1463808 bytes)

Closes #11130

Previously you could only Copy(To), not CopyFrom.

Implies that some Assets can be written to instead.
This is the opposite command of "minikube image load",
and can be used after doing a "minikube image build".

The default is to save images in the cache, but it is
also possible to save to files or to standard output.
