Fixes Ansible Vagrant for CoreOS
Fixes Ansible Vagrant for CoreOS

Previously, Vagrant would not properly set the box download
url:

kube-node-1: Downloading: https://storage.googleapis.com/\
.release.core-os.net/amd64-usr//coreos_production_vagrant.json

An error occurred while downloading the remote file. The error
message, if any, is reproduced below. Please fix this error and
try again.

The requested URL returned error: 400 Bad Request

This commit properly sets the coreos update_channel
and image_version variables.
