Add minikube image commands for pull and tag and push

[afbjorklund]

There are lots of copy and paste in these, so the whole "image" and "machine" is due for an overhaul.

There are also no tests that they actually work, but they are normally not called separately by the user...

Closes #12323

See #12270 (comment)
