feat: Implement Replicated Local Key-Value Store with Node-Local Ownership

[giangndm]

This PR introduces a replicated local key-value store (local_kv) that distributes data across all nodes in the cluster while maintaining node-specific data ownership.

Key Features:

• Data is automatically replicated to all nodes in real-time
• Each key-value pair is created and primarily owned by its originating node
• Provides local-speed data access across the cluster
• Automatic data cleanup when a node disconnects

Use Cases:

• Distributed session management
• Temporary distributed caching
• Node-specific metadata sharing

Implementation Details:

• Broadcast mechanism ensures immediate data synchronization
• Data is automatically removed from other nodes if the originating node disconnects
• Designed for scenarios requiring fast, transient, node-local data distribution

Considerations:

• Data consistency is eventual
• Not suitable for critical or persistent data storage
