Support for dual-stack IPv4/IPv6 App Gateway

[rg54]

Since March 2024, Application Gateway support for dual stack (IPv4 and IPv6) front-end connections from clients is generally available : https://stackfeed.io/article/2024-03-20-generally-available-application-gateway-v2-ipv6-support/

But according to official documentation, AGIC currently doesn't support IPv6 front-end configurations.

With more and more IPv6-only mobile devices, it becomes essential to support both IPv6 and IPv4 between clients and front-end components (particularly for mobile-connected IoT devices, like on the project I'm currently working on).

And the possible workarounds have major drawbacks :

• replacing AGIC by another non Azure-managed ingress controller
• adding another IPV6-compliant component as front-end (like Front Door), with additional Azure cost
