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.
As above, it might be more helpful to the general public if we could do this on openSUSE. Not a reason not to merge, just sayin'.
