Code Review
This pull request updates ComputeEngineCredentials to handle 403 Forbidden responses during the Compute Engine metadata server ping check by immediately returning false instead of logging an unexpected exception. It also introduces a new test case to verify this behavior and adds request counting to MockMetadataServerTransport to ensure no retries occur. There are no review comments, and I have no additional feedback to provide.

Don't retry GCE Metadata 4xx errors which are generally non-retriable errors and only adds startup noise/latency by retrying 3 times.
