[chef] Add new admin user via chef 12 CLI

[Douglas Garstang < >]

How do I create a user with chef 12 and give that user admin rights? The docs have you create user first, and then create an org and associate the user as admin in that org. Well, I did that, and now I'd like to create another admin user. However, since the org has already been created, what do I do? How do I add another admin to an existing org?
