🎉 Major New Feature: IPAM Support

This release introduces comprehensive IP Address Management (IPAM) support through Azure Virtual Network Manager, enabling centralized IP governance and automatic conflict prevention.

✨ New Capabilities

• 🏢 VNet IPAM Allocation - Automatically allocate VNet address space from centralized IPAM pools
• 🔗 Subnet IPAM Allocation - Dynamic subnet addressing with automatic conflict resolution
• 🔀 Mixed Addressing - Combine IPAM and traditional subnets within the same VNet
• 🔄 Enhanced Subnet Module - Standalone subnet module now supports IPAM allocation
• ⚡ Retry Logic - Robust conflict resolution with 15-second intervals (300s max timeout)

📍 Regional Availability

IPAM is supported in all Azure regions where Virtual Network Manager is available, except: chilecentral, jioindiawest, malaysiawest, qatarcentral, southafricawest, westindia, westus3

🛠 What's New

Core Module

• Added ipam_pools variable for VNet address space allocation
• Enhanced subnet configuration with IPAM pool support
• Integrated retry mechanisms for reliable IPAM operations
• Maintained full backwards compatibility (zero breaking changes)

Subnet Module

• Added IPAM allocation capabilities to standalone subnet module
• Support for dynamic IP assignment from IPAM pools
• Consistent interface with main module IPAM features

New Examples

• ipam_basic - Complete IPAM usage with VNet and multiple subnets
• existing_vnet_ipam_subnets - Adding IPAM subnets to existing IPAM-enabled VNets
• ipam_vnet_only - IPAM VNet creation with traditional subnet management

🔧 Technical Requirements

• Azure Virtual Network Manager required for IPAM functionality
• azapi provider version ~> 2.4
• Removed time provider dependency (replaced with native azapi retry logic)

📚 Migration Notes

• No breaking changes - existing configurations work unchanged
• Optional feature - IPAM can be adopted gradually alongside traditional addressing
• State compatibility - no state migration required

🐛 Other Improvements

• Enhanced error handling and retry mechanisms
• Comprehensive documentation and troubleshooting guides
