Allow X-Request-ID header to be set in response
This change will allow the LabKit middleware (Handler) to be configured to send the Correlation-ID value in the X-Request-ID header in the response headers.
This could be useful for reporting and allowing users to better report and track errors, and support and production engineers to track issues.
