When running with newer `google-auth` lib (googleapis/google-auth-library-python#1856), the default behavior is to access the https endpoint of the metadata server. This is causing cert errors like the following: ``` // The spack installation comes with a build-cache hosted on a gcs bucket spack install [email protected] +lustre ^[email protected] fabrics=ucx ^[email protected] +verbs +rdmacm +rc +ud +thread_multiple ==> Error: Failed to retrieve https://metadata.google.internal/computeMetadata/v1/instance/service-accounts/default/?recursive=true from the Google Compute Engine metadata service. Compute Engine Metadata server unavailable. Last exception: HTTPSConnectionPool(host='metadata.google.internal', port=443): Max retries exceeded with url: /computeMetadata/v1/instance/service-accounts/default/?recursive=true (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1004)'))) ``` This PR adds the `GCE_METADATA_MTLS_MODE` env-var to avoid accessing the https endpoint.
