Gets the daemon generation required for creation, or null for endpoint-scoped creation.

Use a generation obtained from <see cref="Server.InspectAsync(CancellationToken)" />
to refuse creation on a replacement daemon. An absent daemon is never
started and its configuration is not loaded. Cannot be combined with
<see cref="ReplaceExisting" />.
