What type of PR is this?

/kind bug

What this PR does / why we need it:

In kubernetes, we get credentials from the metadata server on GCE VMs:
https://github.com/kubernetes/kubernetes/blob/v1.15.0-alpha.2/pkg/credentialprovider/gcp/metadata.go
The credentials are used to pull container images.

But it checks whether it's running on GCE VM by looking at a Linux specific file, which not works on Windows. This PR added the check for Windows node.

Determine system model to get credentials for windows nodes.

Hi @liyanhui1228. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Looks like the test failures are related to this. Not sure why it didn't pick up those fixes.

I checked with a couple team members and they approved this approach. There's a small chance the result will be different in a shielded VM (with UEFI firmware instead of BIOS) - I'll test it out and will let you know if there's a difference (but don't block merge on this).
