feat: enhance retry configuration with exception filtering and delay options

[mandel]

Summary

This PR enhances the retry configuration system with advanced exception filtering and delay management capabilities.

Changes

• RetryConfiguration class: New configuration class with comprehensive retry options
• Exception filtering: Support for filtering specific exception types (single or list)
• Delay management: Added delay, max_delay, backoff, and jitter parameters
• Backward compatibility: Maintains support for integer retry values
• Comprehensive tests: Added extensive test coverage for all new features

Key Features

1. Exception Filtering: Retry only on specific exception types
2. Exponential Backoff: Configurable backoff multiplier between retries
3. Max Delay: Cap on maximum delay between retries
4. Jitter: Random or fixed jitter to prevent thundering herd
5. Backward Compatible: Existing integer retry values continue to work

Testing

• Added with 9 comprehensive test cases
• Extended with delay and timing tests
• All tests verify correct behavior of new features
