This API will let you update any Role, including its assocaited permissions. All organizations in the AuthGroup will be affected by this API, be careful. There is a non-standard way of associating a permission to a Role. The property "permissions" takes an array of strings comprised of a concat of the Permission Ids and the Permission code. As an example, "3fa85f64-5717-4562-b3fc-2c963f66afa6 user::read:own" would be one string entry.
