Reading special DMI vendor information files may easily break up in future cloud provider’s virtualization implementations.

For example, ai.backend.common.identity.detect_cloud() function does not work on the latest Microsoft Azure VM instances (e.g., DSads v5).

Let’s consistently use the metadata URL (without relying on DNS resolution) 169.254.169.254 to detect the cloud provider type, using asyncio.staggered.staggered_race() to run the multiple detection routines like the happy eyeballs mechanism.
