Description of problem:

The last rebase of the AzureDisk CSI driver broke OpenShift on AzureStackHub (ASH). We should have a job for ASH in the CSI driver repos and the job should run automatically at least in both AzureDisk and AzureFile driver rebases (ASH quota is small).

Our CI allows to run a job (like ASH) on a PR that change a specific file (run_if_changed here). If we know that every rebase changes a certain file, we can configure CI to run ASH tests on PRs that change that file.

It seems AzureDisk hardcodes the driver version in their Makefile, would it be a good target?
