chef-provisioning-docker doesn't implement :destroy for machine_image

I'm not sure how it fits into idiomatic Docker workflows, but since it's doable with the CLI docker tool, it seems like an obvious thing for us to have.

It seems it just needs to be added. See https://github.com/chef/chef-provisioning-docker/blob/master/lib/chef/provisioning/docker_driver/driver.rb#L164

Yep. I may put it into 0.7 with your fixes for chef-provisioning 1.x.

This feature seems is not blocked by chef-provisioning 1.x compatibility issue. So, I'm not sure if you need to include my changes, since I didn't get any feedback from @jkeiser or @tyler-ball regarding to my PR so far. So we don't know when it will (if it will ever) get into master.

@marc- we appreciate all the work you got together in #47 - we're going to get it merged. We have a couple of people new to Docker so we're all trying to get up to speed on that PR. Sorry we have been unresponsive for a while!
