Add name to metadata

Add a name to metadata.rb to solve this issue: 
```
Berkshelf::BerksError: Berks command Failed: /usr/bin/berks vendor /Users/jirwin/.berkshelf/default/vagrant/berkshelf-20141025-1891-1isqcby-default --berksfile=/Users/jirwin/projects/vagrantChefTest/Berksfile, reason: Ridley::Errors::MissingNameAttribute The metadata at '/var/folders/y_/bsdtkf153k5bmmts8f0_00th0000gn/T/d20141025-3383-1x28x9t' does not contain a 'name' attribute. While Chef does not strictly enforce this requirement, Ridley cannot continue without a valid metadata 'name' entry.
```
