Connection Pool and Retry Logic

Difficulty: ⭐⭐ (Easy-Medium)
Dependencies: Issue #6 Component: Cluster Connection

Description: Implement robust connection pooling and retry mechanisms to handle transient network issues and improve reliability when working with multiple clusters. Create a connection pool that maintains persistent connections to frequently accessed clusters, implement exponential backoff retry logic with configurable maximum attempts for failed requests, and add comprehensive connection timeout configuration at multiple levels (connection, request, overall operation). Include connection health monitoring that periodically checks cluster accessibility and marks unhealthy clusters, implement intelligent connection caching to reuse connections within operations, and add a circuit breaker pattern that temporarily stops attempting connections to consistently failing clusters. Provide detailed connection metrics and add support for connection preemption to handle rate limiting scenarios.

Acceptance Criteria:

• Implement connection pooling for multiple clusters
• Add exponential backoff retry logic
• Support connection timeout configuration
• Add connection health monitoring
• Implement connection caching
• Add circuit breaker pattern for failing clusters

Why Now: Enhances the connection management established in Issue #7.
