      Hi,

      I've spotted an incompatibility issue of the association's :touch option.
      While ActiveRecord association accepts a symbol specifying the timestamp attribute to update, Mongoid only updates updated_at disregarding the :touch option value.

      Example:

      class Post
  include Mongoid::Document
  include Mongoid::Timestamps

  field :title, type: String
  field :tags_changed_at, type: Time

  has_many :tags
end

class Tag
  include Mongoid::Document
  include Mongoid::Timestamps

  field :name, type: String
  belongs_to :post, touch: :tags_changed_at
end

p = Post.create(title: 'Party hard')
t = p.tags.create(name: 'beer')
p.tags_changed_at # => nil

      This can be fixed in Mongoid::Relations::Touchable#define_relation_touch_method by accepting optional :touch value.

      Should I open a pull request or there's somebody who can take this on?
