Add reorg handler functionality and configuration options

[iuwqyir]

TL;DR

Added a new reorg handler to detect and handle blockchain reorganizations.

What changed?

• Introduced a new ReorgHandler component with configuration options
• Added reorg detection logic to scan for inconsistencies in block headers
• Implemented a fork point detection mechanism
• Created a process to handle reorgs by re-fetching and updating affected blocks
• Added new metrics for tracking reorg handler performance
• Updated the orchestrator to include the reorg handler in its workflow

How to test?

1. Enable the reorg handler using the --reorgHandler-enabled flag or REORGHANDLER_ENABLED environment variable
2. Configure the reorg handler settings:
   • Interval: --reorgHandler-interval or REORGHANDLER_INTERVAL
   • Blocks per scan: --reorgHandler-blocks-per-scan or REORGHANDLER_BLOCKSPERSCAN
   • Starting block: --reorgHandler-from-block or REORGHANDLER_FROMBLOCK
   • Force starting block: --reorgHandler-force-from-block or REORGHANDLER_FORCEFROMBLOCK
3. Run the indexer and monitor the logs for reorg detection messages
4. Check the new metrics reorg_handler_last_checked_block and reorg_handler_reorg_counter for reorg handler activity

Why make this change?

Blockchain reorganizations can lead to inconsistencies in indexed data. The reorg handler ensures data integrity by detecting reorgs and updating the affected blocks, maintaining the accuracy of the indexed information.
