[Profiler] Add detailed request time desc. (dns lookup, ...)

[florianpreusner]

Based on #210:

More detailed request time description: dns lookup time, connection time, etc..

This sounds awesome, but where could we get that information? I've searched for a bit, but couldn't find anything on how to retrieve these timings from Guzzle.

@rpkamp sorry for long answer. I checked and found that in RequestTimeMiddleware we're using on_stats option from guzzle. There we receive TransferStats object with handler stats info via getHandlerStats and getHandlerStat methods. That's an example of info:

Guzzle receives these info from curl getinfo function: https://www.php.net/manual/en/function.curl-getinfo.php

Hope it will help you 🙂

Yeah, but how to access request time in symfony log middleware, for example, to put it in log context...
