Refactor Packer README, use manually wrapped lines

As Vracko pointed out on the last review that touched
this README, using long lines and allowing an editor
to handle the wrapping doesn't work well in Gerrit.

Markdown will render both versions equivalently.

-OpenDaylight's current use-case for Packer is to build an ODL Vagrant base box, provisioned using upstream deployment/config tools. Reusing the logic of our configuration management tools nicely standardizes our deployment story, enabling good code reuse and separation of responsibilities. Providing an upstream Vagrant base box prevents all ODL consumers from duplicating ODL download, install and configuration logic, data transfer and computation in every Vagrantfile we create.
