Nit: Maybe rename to something with Cloud to make it clearer and to keep
symmetry with the AD counterpart?

What would you think about:
SetConsumerOwned()
SetCloudManaged()
SetActiveDirectoryManaged()

For better or worse, AD install attributes contain device_id.  Therefore I think
it would make sense to add that here.

Done.
