Which problem is this PR solving?
Since the HotROD UI does not start traces, it can only search for a trace corresponding to a particular request by some span tags. This makes the experience of opening a trace a big clunky as we first see the search page with one trace, and then have to click on the trace again.

Short description of the changes
Change the HTTP instrumentation to always generate a
traceresponseheader per the current W3C draft. Then parse the trace ID from that header in the UI and generate a hyperlink to open the trace view directly, bypassing the search.
