Backport of kubernetes-sigs#2380 to release-1.27. Adds Azure Container Linux (ACL) support across the blobfuse-proxy installer flow by detecting ACL via VARIANT_ID and ensuring binaries are installed into the correct host path, while also extending OS detection utilities to expose the variant. Changes: - Extend util.OsInfo / GetOSInfo() to parse VARIANT_ID from /etc/os-release - Default blobfuse-proxy to Blobfuse v2 on Azure Container Linux - Treat ACL like RHCOS/Flatcar/Garden Linux for installer handling and Helm hostPath mounts (/var/bin)
