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.
True, I haven't been keeping it up to date. (I tend to remove changelog files from my projects these days since bah, read the git log people! ;))
