az ad app permission admin-consent fails

[rbankole]

Thanks for this repo....helped us a bunch! Issue we rant into -: When running the az commands for the admin-consent, this works if you're using a local az user but when running in a pipeline (non-interactively), it fails as the pipeline is using a service principal for auth. Basically, this will not work if using service principals. Our workaround is to use a local user to auth az cli, then run the tf script.
