Sometimes, puppeteer (or the underlying CDP session) don't notify us
when a request finishes. This makes the scenario stuck indefinitely.

This commit improves the situation by:

* listening to the `response` event (it has been observed that
  sometimes `requestfailed` and `requestfinished` are not notified, but
  `response` is)

* adding a 5 seconds timeout to all requests

It seems like following the puppeteer upgrade (maybe because it uses a
different Chromium version), the Chrome Devtools `Profiler` profile is
reset on each page navigation. Thus, we lose some precious information.

This commit fix it by stop/start the profiler more often, aggregating
the different resulting profiles.
