L1VH CNI changes for Swiftv2

[paulyufan2]

Reason for Change:

This implementation is to support swiftv2 L1VH CNI feature: CNI receives goal state from CNS and create linux/windows pod on Windows VM/Node in swiftv2 L1VH path; The container pod is using secondary interface with its mac address and NIC type(Delegated NIC or Accelnet) to be created; We support up to 8 pods to be created by using different interfaces along with different hnsNetwork; CNI supports hnsNetwork creation(when pod is added to the VM) and deletion(when pod is removed from VM) to prevent leakage;

Issue Fixed:

Requirements:

• [ ] uses conventional commit messages
• [ ] includes documentation
• [ ] adds unit tests
• [ ] relevant PR labels added
