Vagrant integration

To get into hawk development quite easy i have started to integrate vagrant and chef provisioning for a multinode setup.

Currently this setup is still missing an automated start of the development environment but you can already see in which direction it gets with a nice vagrant integration.

If the pull request is fine i can squash the commits for a clear git history.
This still does not really work. @tserong maybe you know better how to allow these command for the user vagrant within the vagrant environment as well.
