SDCICD-1804 Fix S3 upload failure on GCP clusters

[YiqinZhang]

• S3 artifact uploads fail on GCP clusters because the cluster's cloud provider region (us-east1, GCP format) is used as the AWS S3 region, producing an invalid endpoint s3.us-east1.amazonaws.com.

• Add a logsBucketRegion constant (us-east-1) in s3.go, co-located with the existing logsBucket constant.

• Use sess.Copy() to create a region-overridden S3 session that keeps the shared AWS credentials but always targets the correct bucket region, independent of the cluster's cloud provider.
