Fangmin Lv updated ZOOKEEPER-2879:
----------------------------------
Description: 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. (was: Dynamic config requires observer has unique
