AWS X-Ray daemon update v2.1.1

This version of the AWS X-Ray daemon fixes an issue where the daemon overrides the customer provided IAM role ARN configuration with the IAM role assigned to EC2 instance profile if a region wasn’t specified in the configuration. We recommend updating to the latest version at the earliest. The latest version of the daemon is available at https://docs.aws.amazon.com/xray/latest/devguide/xray-daemon.html
