Add rake task that can be used on CI

[pivotalcommon]

As a developer
I want to be able to add a rake task to my CI build that will fail if there are license action items to address
So that I don't inadvertently add a dependency to my app that the client doesn't want

One option would be to add a new rake task like so:

namespace :license do
  desc 'checks whether there are action items and returns a 0 or a 1 - useful for ci'
  task :check => :generate_dependencies do
    action_items = LicenseFinder::Finder.new.action_items
    if action_items.present?
      puts "License action items:", action_items
      exit -1
    else
      exit 0
    end
  end
end

The other option would be to update the license:actions task to exit with a non-zero return code if there are any actions to take.

This can be achieved by using rake action_items:ok.
