------------------------------------------
Summary: Support a new comprehensive parent znode watcher
Key: ZOOKEEPER-3815
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3815
Project: ZooKeeper
Issue Type: New Feature
Reporter: Mohammad Arshad
Assignee: Mohammad Arshad
When a client registers this new watcher(for time being lets call it
comprehensive parent znode watcher, we can give better name later.) on a parent
znode then
# Client should be notified on following events
## When a child is added
## When a child is deleted
## When a child is updated
## When parent is deleted
# Client should be notified with znode data, This should be optional. There are
many scenarios where znode data is always required. This can avoid unnecessary
RPC calls.
# If Client keeps all child znode data in memory, there should be way to check
whether client data is consistent with Zookeeper server data. This is to ensure
that no notification is lost.
# This watcher should be persistent watcher, not one time watcher
