feat: [torrust#697] add logs to HTTP tracker

Sample logs:

```
2024-02-19T13:00:12.631712627+00:00 [HTTP TRACKER][INFO] request; method=GET uri=/health_check request_id=24a3f4a2-99e5-4db1-890f-f7196a294c2a
2024-02-19T13:00:12.631765246+00:00 [HTTP TRACKER][INFO] response; latency=0 status=200 OK request_id=24a3f4a2-99e5-4db1-890f-f7196a294c2a
```
