Add metrics for zip serving
Zip serving package implements the type Serving interface
. We should add some metrics to serve from zip archives similar to #365 (closed) so that we can track and compare serving times from archives vs disk.
- ZipServingOpenArchivesTotal
- ZipServingFilesPerArchiveCount

I think we should for OS access have a histogram of timings of different request stages, like: connection, tls handshake, response write, response to the first byte, response read. This would allow us to understand how responsive is OS on different stages. (edited)
Also, for caches we should have hit/miss metric, and amount of cache entries
