Pull Request Overview

This PR updates the symmetric routing functionality in Terway by restructuring the networking configuration code. The main purpose is to replace the previous portmap-specific network configuration with a more general symmetric routing implementation that supports dual-stack networking (IPv4 and IPv6).

• Replaces the portmap.go implementation with a new symmetric.go module that handles both IPv4 and IPv6 network rules
• Adds configurable symmetric routing through SymmetricRoutingConfig structure in CNI configuration
• Expands test coverage with comprehensive test suites for network utilities and symmetric routing functionality
