Add CloudPassage and New Relic chef recipes

I have omitted our license keys, but upon adding them New Relic will work. 

CloudPassage, however, does not detect the license key even if you provide a valid one. This needs fixing but the groundwork is there. I'm not sure why it isn't working as I'm following the cookbook's instructions. CloudPassage logs are in /opt/cloudpassage/logs/, and you must be super user to view them on the vagrant box.
