This adds a lightweight form of tracing to GTS. Each incoming request is assigned a Request ID which we then pass on and log in all our log lines. Any function that gets called downstream from an HTTP handler should now emit a requestID=value pair whenever it logs something. Co-authored-by: kim <grufwub@gmail.com>
