Request ID is essential in operating OpenStack services, especially when troubleshooting some API problems. It allows us to find out the log lines actually related to a specific request. However watcher api hasn't returned it properly, so operators had no way to determine the exact ID they should search. Add RequestID middleware to return the id in X-OpenStack-Request-Id header, which is globally used.
