Allow to return `{:ok, data}` from authorize callbacks?

Hi!

I am thinking about about possibility to provide some extra context for permissions. Like not the just fact that user can do something but also why. Something like this:

def authorize(:edit_post, user, post) do
  cond do
    user.is_admin -> {:ok, :admin}
    post.user_id == user.id -> {:ok, :author}
    true -> {:error, "Only adminisrators and authors can edit posts."}
  end
end

I am thinking about preparing PR but does not make sense if you think it don't fit into lib scope etc.

Not saying you should not do this, but honestly I would keep the "why" closer to the surface. Like the controller. The reason is you may want to responds according to your interface later.

This would unfortunately break the core API specification and would require a major version bump per SemVer, which is just not in the cards right now. And also I agree with @joshchernoff that this is solving an issue different from authorization. Thank you for the proposal.
