Martin, can you think of more metrics we should add later?

I'm pretty happy about what we have now.
You may add statistics about average response time and I would like to see
stats per request type (e.g. http_responses_transfer_bytes_count for debuginfo,
source, binary, ...).

Response time (within debuginfod code proper, as opposed to the subsequent file
transfer) is exposed with the http_responses_duration_milliseconds_* metrics. 
Total file transfer time would have to be calculated by extracting extra
information/callbacks from libmicrohttpd.

The response time is more a wish. What's the most important is the progress
indication that can a consumer get in gdb, or other tool.
For now, I wouldn't spend time with more metrics.
