Bug Fixes

Handle race condition for /step endpoint of metadata service.

The foreach step in AWS Step Functions launches multiple AWS Batch tasks, each of which tries to register the step metadata, if it already doesn't exist. This can result in a race condition and cause the task to fail. This patch properly handles the 409 response from the service.
