Replace Monolog middlewares by an event listener

This is an alternative to the changes introduced by #894 in order to allow replacement of the logging middlewares.
Instead of having a Closure for each listener, this PR introduces a listener class.
The listener can be used independently from the MonologServiceProvider.
