Implement Nonce Request Interface with Robust Client Support

Original Task

Design Nonce Request Interface

Summary of Changes

This pull request introduces a comprehensive Nonce Request Interface designed to provide a flexible and robust mechanism for obtaining nonce values across different client types.

Key Changes:

• Created abstract interface for nonce request
• Defined clear method signature for get_nonce()
• Implemented flexible error handling
• Added comprehensive documentation
• Developed unit tests to ensure interface contract

Acceptance Criteria

Interface defines get_nonce() method with clear return and error types
Abstract method includes provisions for different client types
100% code coverage for interface definition
Interface documentation explains usage for each client type
Unit tests validate interface contract and error handling

Tests

• Verify get_nonce() method returns expected nonce value
• Validate error handling for different client scenarios
• Ensure interface can be implemented by various client types
• Check that method signatures match the defined contract
• Confirm 100% code coverage for interface definition
