Pull request overview

This PR introduces infrastructure and configuration for a new CNI (Container Network Interface) prototype scenario in the perf-eval category. The changes enable testing of ipvlan CNI with stretch clusters by providing Terraform configurations for both Azure AKS and AWS EKS deployments, along with shell scripts and ARM templates for setting up dual IP configurations on VMSS nodes.

Key Changes:

• Added Terraform configuration files for deploying CNI prototype test scenarios on Azure and AWS
• Modified Azure network module variables to support multiple address spaces and prefixes (changed from string to list(string))
• Added shell scripts for stretch cluster setup with ipvlan CNI configuration
• Reduced EKS addon timeout defaults from 20m to 5m
