Create ingredient_config resource

[jtimberman]

Render configuration files, use the config property from the ingredients:

chef_ingredient "chef-server" do
  config api_fqdn: node['fqdn']
  action [:install, :reconfigure]
end

ingredient_config "chef-server" do
  notifies :reconfigure, "chef_ingredient[chef-server-core]"
end

• Add to the product_matrix the location of the main configuration file (/etc/opscode/chef-server.rb for chef-server, etc)
• Use a helper method that stashes the configuration in node.run_state[:product_name_config] - oc-lita style
• Also need to create the configuration file's directory, e.g. /etc/opscode
• Modify chef-server to use ingredient resource to replace the configuration file via template
