Vagrant support for Orion

Have you ever wanted to have an Orion Context Broker ready to develop in your machine easily?
Run:

    vagrant up

You just need to install Vagrant if you want to use this, no new dependency added. Especially useful for those like me that use virtual machines to develop on a Mac or a Linux that is not CentOS.

After a few minutes (10 in my machine) you can ssh into the machine (vagrant ssh) and run contextBroker. It will be accessible in 127.0.0.1:1026.

The bootstrap script basically goes through the installation instructions in the README.
This is some kind of reference to a public Valgrand library of operating systems? At, we don't any "chef/centos-6.5" in our repo...

By the way, I think we should use CentOS 6.3 in this file (remember what README.md says: "Orion Context Broker reference distribution is CentOS 6.3"), althoug we could mention how how to set other operating systems in the Valgrind section of the README.md file.
