### Rationale for this change The default constructor of the `ClientConfiguration` class in the AWS SDK can issue spurious EC2 metadata requests to resolve the current region, even if we would later set the region from our S3 options. ### What changes are included in this PR? 1. Avoid spurious EC2 metadata calls by disabling "IMDS" in the `ClientConfiguration` constructor 2. Change the smart defaults from "legacy" to "standard" (see https://docs.aws.amazon.com/sdkref/latest/guide/feature-smart-config-defaults.html) 3. Let the user configure the smart defaults in `S3Options` ### Are these changes tested? By existing CI tests and configurations. ### Are there any user-facing changes? The default S3 settings are potentially changed. Hopefully this will not trigger any regression in behavior. -- This is an automated message from the Apache Git Service.
