Description

From Java docs:

When a client drops the current connection and re-connects to a server, all the existing watches are considered as being triggered but the undelivered events are lost. To emulate this, the client will generate a special event to tell the event handler a connection has been dropped. This special event has EventType None and KeeperState Disconnected.

Contributor guide

Research direction
Investigate how the global watcher stream is implemented and trace where connection state changes are handled to generate the special None/Disconnected event upon reconnect.
