Since Nov 16, 2021, we have the following conventions:
- Drivers published from tip-of-tree have an `-alpha` version and are
stored at `/next` subfolder on Azure Storage.
- Drivers auto-published for each commit of the release branch have a `-beta` version and are
stored at `/next` subfolder on Azure Storage.
- Drivers published due to a release might have `-rc` as part of the
version, and are stored in root subfolder on Azure Storage.
We no longer have driver versions that include "next" as part of the
version. I kept it for backwards compatibility.
