> Dynamic config requires observer has unique server id, which means we cannot
> simply add observer with dynamic server id -1. For large observer cluster,
> it's much more easier to add observer without unique server id if it doesn't
> need to be promoted to participant. Also, it will make dynamic config more
> efficient, we don't need to store and send the long list of observers during
> re-config.
