Automate Azure Identity SDK Manual/Vendor Tests

[joshfree]

We should leverage @christothes 's work on https://github.com/Azure/azure-sdk-for-net/pull/33017/files to fully automate the list of manual/vendor test scenarios which are documented in the issues here: https://github.com/Azure/azure-sdk/issues?q=is%3Aopen+is%3Aissue+label%3AAzure.Identity

This includes:

• [x] Automate Azure Arc testing
  • Currently not worth the ROI on automating.
• [x] Automate Azure Identity multi tenant testing
• [x] Automate Azure Kubernetes Service
  • https://github.com/Azure/azure-sdk-for-python/pull/33742
• [x] Automate Azure Container Instances testing
  • Similar coverage is already completed with AKS testing
• [x] Automate Azure WebJobs testing
  • Web Apps covered in lieu of WebJobs (still App Service)
  • https://github.com/Azure/azure-sdk-for-python/pull/33742
• [x] Automate Azure Service Fabric testing
  • Currently not worth the ROI on automating.
• [x] Automate Azure Functions testing
  • https://github.com/Azure/azure-sdk-for-python/pull/33742
• [x] Automate VM MSI testing
  • https://github.com/Azure/azure-sdk-for-python/pull/34070
• [x] Automate Pod Identity testing
  • Deprecated. Will be covered by AKS workload identity testing
• [x] Automate Cloudshell testing
  • Requires manually navigating to a cloud shell, and not sure how to automate.

Closing this as completed. Can revisit Arc and Service Fabric test automation separately if we determine it's worth the ROI.
