Subject: mobileactivation: Allow passing activation response headers as
 required for iOS 11.2+

When activating in session mode - which is required for newer iOS versions -
we can now pass the activation response headers with the activation command.
For iOS 11.2+ this is mandatory or the activation will fail.
