1. Fixed issue with attribute where there wasn't a trailing slash ( thanks @mannytoledo ). If you don't believe me, goto http://yum.datadoghq.com/rpm then try going to http://yum.datadoghq.com/rpm/

2. Bumped up metadata version to ~> 0.2. This is non breaking, but `bescarlett` needs a recipe in bepython `0.2.0`

NOTE: THERE IS NO RUBOCOP FILE IN HERE TO OVERRIDE OUR RULES, DUE TO THAT, THIS WILL NOT BE ADDED TO THE DEV CHEF SERVER AUTOMATICALLY, IT WILL FAIL.

Not sure what should be done about that.
