X-Ray extension pulls from DockerHub instead of ECR, cannot use in private isolated VPC

[kevinschwarz]

The current X-Ray extension uses the image "amazon/aws-xray-daemon" instead of "xray/aws-xray-daemon". To be able to pull images in a private isolated VPC via VPC Endpoints, the image has to target ECR instead of docker hub. Can this image be updated to point to the ECR version?
