Knife Spork Promote Improvement

[TheSerapher]

I was wondering if knife spork could be improved. Instead of having the cookbook to be promoted in the cookbooks folder, use the Chef server instead to get a list of cookbooks and either pin the latest version available or a user defined version that has to exist on the chef server.

This would help in releasing cookbooks since we won't need to add each cookbook to promote into the Chef folder and could rely on Chef Server data instead.

Just an idea.
