Support For Privacy Flag For Supermarket

[echohack]

In reference to issue: chef/supermarket#832

Currently Berkshelf throws an error if you try to do berks install with the privacy flag set in your metadata:

MyComputerName:my_cookbook echohack$ berks install --debug
An error occurred while reading the Berksfile:

  Could not parse `/Users/dechols/chef/vertafore-base/metadata.rb': undefined method `privacy' for #<Ridley::Chef::Cookbook::Metadata:0x007fbd717c9a80>

I suspect that ridley/chef/cookbook/metadata.rb needs another attribute added for privacy.

@echohack this isn't a part of Chef's metadata so it didn't make it into the Ridley update that corresponded with Chef 12. If this is merged into Chef core then we can add the support but we really don't want to create divergent tools where only Berkshelf / Ridley understand how to process the metadata while Knife doesn't.

Here's the issue to add it to Chef's metadata.

Right, but it's not an accepted pull request. Ping back here once it is accepted ;).

Looks like that PR got merged in back in August. I just ran into the same issue today.

[thommay]

this got merged in March to ridley.
