Add glue to make it easy to use subscription-manager with vagrant.
Add the ability to unsubscribe in the right place.

This is useful to avoid polluting your subscription account with unused
entitlements. This also moves around the destroy code so that the box
can be introspected.
Make it easy to enable additional repos per vm.

This is useful for adding things like: rhel-7-server-extras-rpms.
Be wordy with unsubscribe message.
Rename project to something shorter and less stupid.

It's still so early, so nobody will mind the name change. Hope this ends
up making devops easier.

Happy hacking!
