The Vultr provider currently never calls handleSSH, resulting in it
being impossible to bring up a LinuxKit image in vultr with the SSH
pubkey provided via the Vultr metadata API.

Vultr uses a very similar approach to AWS, including using the
same IP address for serving metadata. In fact, it seems
as though if AWS appears first in the list of providers, that
provider mistakenly believes to be running on AWS (hence the
insertion of `NewVultr` in between GCP and AWS. I don't believe
AWS servers will accidentally try to use the Vultr provider,
as it seems that the `/v1/` endpoint doesn't exist on AWS.
