Introduce into_manager for Device

To enable applications like nitrokey-test to go back to a manager
instance from a Device instance, we add the into_manager function to the
Device trait.  To do that, we have to keep track of the Manager’s
lifetime by adding a lifetime to Device (and then to some other traits
that use Device).
