Discussion
----------

Add logger and stopwatch for Doctrine queries

Add SQL queries to the logs using the DbalLogger of the DoctrineBridge.

In addition, if the WebprofilerServiceProvider is registered (stopwatch service set), the timeline show doctrine queries.

I'm wondering if the stopwatch service should be moved to Silex core.

Totally 👍 for moving it to silex.

Is there a use case for the "stopwatch" outside of the webprofiler ?

@GromNaN Yes, it you want to bench some code.

@fabpot please not it will only add cruft. i think it is a niche thing to use the Stopwatch component.
