Add support for other redis connection types

[delano]

Description
We want to add support for more redis connection types like Redis Cluster is one example to improve scalability and high availability. This will allow us to:

• Horizontally scale Redis across multiple nodes
• Enable automatic sharding
• Support data partitioning across nodes
• Improve overall system reliability

Implementation Details

• Set up a 3-node Redis Cluster configuration
• Configure Redis client to support cluster mode
• Update application code to handle cluster operations
• Add documentation for cluster setup and management

Technical Requirements

• Redis version 7
• Cluster mode enabled on all nodes
• Client library with cluster support

Docker Configuration
Below is the docker-compose configuration for a 3-node Redis Cluster:

services:
  redis-1:
    image: redis:7
    command: redis-server --port 7000 --cluster-enabled yes --cluster-config-file nodes.conf --cluster-node-timeout 5000
    ports:
      - "7000:7000"
      - "17000:17000"
    networks:
      - redis-net

  redis-2:
    image: redis:7
    command: redis-server --port 7001 --cluster-enabled yes --cluster-config-file nodes.conf --cluster-node-timeout 5000
    ports:
      - "7001:7001"
      - "17001:17001"
    networks:
      - redis-net

  redis-3:
    image: redis:7
    command: redis-server --port 7002 --cluster-enabled yes --cluster-config-file nodes.conf --cluster-node-timeout 5000
    ports:
      - "7002:7002"
      - "17002:17002"
    networks:
      - redis-net

networks:
  redis-net:

Cluster Initialization Commands

# Initialize cluster
echo "yes" | docker exec -i data-redis-1-1 redis-cli --cluster create \
  data-redis-1-1:7000 data-redis-2-1:7001 data-redis-3-1:7002 \
  --cluster-replicas 0

# Verify cluster status
docker exec data-redis-1-1 redis-cli -p 7000 cluster info
docker exec data-redis-1-1 redis-cli -p 7000 cluster nodes

Client Configuration Example

redis = Redis::Cluster.new(
  nodes: [
    "redis://localhost:7000",
    "redis://localhost:7001", 
    "redis://localhost:7002"
  ],
  timeout: 5,
  connect_timeout: 5
)

Acceptance Criteria

• Redis Cluster successfully deployed with Docker Compose
• Cluster initialization script works correctly
• Application can connect to and interact with the cluster
• Documentation updated with cluster setup instructions
• Tests added/updated to verify cluster functionality
