ATLAS-3924: Add Comprehensive Documentation for Hive Metastore Hook

[divija21]

ATLAS-3924 :

This PR introduces a new documentation file HookHive.md to explain the Hive Metastore Hook, which was originally implemented under ATLAS-3148 but lacked official usage guidance on the Apache Atlas documentation site that is mentioned in [ATLAS-3924]

The documentation aims to make it easy for users to configure and understand the purpose of the Hive Metastore Hook.

It includes :

1. Overview: Role of the hook in capturing Hive DDL operations (like CREATE/DROP TABLE).
2. Configuration Instructions:

• How to enable the hook via hive.metastore.event.listeners.
  

• Steps to copy hook files into Hive
  

• Update instructions for hive-env.sh and atlas-application.properties.
  

3. Atlas Hook Properties:

• Kafka/Zookeeper configuration
• Threading, retries, and cluster settings

4. How It Works:

• DDL events from Hive are pushed to Atlas Kafka topic .
