- Update minio-go so that we can get a fix for timeouts encountered when trying to retrieve IMDSv2 tokens during IAM s3 authentication. When bazel-remote is run within a container on an aws ec2 instance, initial attempts to authenticate using IAM will encounter a 120s delay. The issue is the result of changes in the ec2 metadata services with IMDSv2, which restricts how many network hops may be incurred before for PUT statements. When executing directly on the ec2 instance, it is 1 hop away, and is allowed. When executing within a docker container on an ec2 instance, it is 2 hops away, and is forbidden. The change to minio go reduces the timeout from 120s to 1s. Apparently this token request is optional, so things continue to work afterward, regardless. minio/minio-go#1626
