[Copilot]

Add Azure Container Storage support and unified FIO testing tool

• Remove AZURE_CONTAINER_STORAGE_TYPE environment variable
• Change default for ENABLE_AZURE_CONTAINER_STORAGE to true
• Remove ephemeralDisk parameter from --enable-azure-container-storage flag
• Refactor FIO Helm chart to support multiple storage types
• Move FIO chart from infrastructure_validations/aks/blobfuse to infrastructure_validations/aks/fio
• Remove Azure Container Storage standalone example
• Embed blobfuse test examples in shared storage documentation
• Remove blobfuse as a storage type option in FIO chart
• Resolve merge conflicts with main branch
• Fix all super-linter issues (including prettier formatting)

Latest Fix:

• Fixed prettier formatting in tools/ai-infrastructure-mcp/README.md (spacing and blank lines)

Original prompt

Add an option for the deploy_aks script to add support for Azure Container Storage:

Here are the docs: https://learn.microsoft.com/en-us/azure/storage/container-storage/install-container-storage-aks

This is the flag: --enable-azure-container-storage when creating the cluster

Add an example for local nvme for the NDv5:

https://learn.microsoft.com/en-us/azure/storage/container-storage/use-container-storage-with-local-disk

@copilot We don't need a type for the container storage (as an env var or when creating aks with az command). The docs should only mention ephemeral - clear up readme. Set default to "true". Make the example a helm chart and reference that from teh main readme

@copilot you do not need ephemeralDisk after --enable-azure-container-storage according to the docs. Please remove it in script and docs

Done in commit f92b683. Removed ephemeralDisk parameter from the flag - now using just --enable-azure-container-storage as per Azure CLI docs. Updated script and all documentation accordingly.

@copilot I don't like the example. Can you update infrastructure_validations/aks/blobfuse/helm/fio to either provide options for the different storage:

• shared_storage (lustre/blobfuse where you pass in the pvc)
• azure container storage
• localpv

Rename to infrastructure_validations/aks/fio/helm/fio. Put the blobfuse example configuations into the docs for the blobfuse shared storage (just embed them rather than providing separate files)

Remove the current azure container storage example.

Done in commit c8b628d:

1. ✅ Updated FIO chart to support multiple storage types (blobfuse, azure-container-storage, localpv, existing-pvc)
2. ✅ Renamed to infrastructure_validations/aks/fio/helm/fio
3. ✅ Embedded blobfuse test examples in shared storage README
4. ✅ Removed Azure Container Storage standalone example directory

The unified FIO chart now supports testing any storage type through the storage.type parameter.

@copilot in the fio example, blobfuse should not be an option - that can be used with the "existingPvcName" option

Done in commit ba94a44. Removed blobfuse as a storage type option. Users should now use existing-pvc with pre-created blobfuse PVCs. Changed default to azure-container-storage.
