Add SSH Key Rotation Feature for Python SDK Parity

[arb8020]

Summary

• Implements SSH key rotation functionality to achieve parity with the Python SDK
• Adds rotateSSHKey() method to the Instance class with comprehensive configuration options
• Includes validation, cleanup, and audit logging capabilities for production security
• Provides comprehensive integration tests covering all rotation scenarios

Features Added

• SSH Key Rotation Method: New rotateSSHKey() method on Instance class
• Security Options: Connection validation, old key cleanup, and audit logging
• Error Handling: Comprehensive error handling for invalid keys and network issues
• Type Safety: Full TypeScript interfaces for options and results
• Integration Tests: Complete test suite covering success and failure scenarios
• Documentation: Detailed usage examples and security best practices

API Changes

New Interfaces

• SSHKeyRotationOptions - Configuration options for rotation
• SSHKeyRotationResult - Result object with rotation details

New Method

async rotateSSHKey(options: SSHKeyRotationOptions): Promise<SSHKeyRotationResult>

Security Considerations

• Only accepts PEM format keys for security and compatibility
• Supports connection validation to ensure successful rotation
• Provides old key cleanup to prevent security vulnerabilities
• Includes audit logging for compliance requirements
• Implements proper error handling to prevent partial rotations

Testing

• Added comprehensive integration tests in test/integration/sshkeyrotation.test.ts
• Tests cover basic rotation, validation, error handling, and security best practices
• All tests follow existing SDK patterns and use the same testing framework

Production Ready

This implementation follows production-grade security practices:

• Input validation for key formats
• Connection testing after rotation
• Proper error handling and rollback capabilities
• Audit logging for security compliance
• Comprehensive test coverage
