Better ManagerWorker :additional_keys & :query_select_keys

[yelled3]

we should split this configuration to:

• query_select_keys
• additional_keys - defaults to query_select_keys

this way, you can add an additional_keys which are not attributes. e.g

class User < ActiveRecord::Base
    def full_name
        "#{first_name} #{last_name}"
    end 
end

class UserSyncerWorker < Sidekiq::ActiveRecord::ManagerWorker
  sidekiq_delegate_task_to UserTaskWorker

  sidekiq_manager_options {
    :query_select_keys => [:first_name, :last_name],
    :additional_keys => [:full_name]
  }
end
