Trace all http requests (#15064)

Browse Source 
Add a generic handler that adds a new tracing context to the request if
tracing is enabled. Other handlers are free to modify the tracing
context to update information on the fly, such as, func name, enable
body logging etc..

With this commit, requests like this 

```
curl -H "Host: ::1:3000" http://localhost:9000/
```

will be traced as well.
