[FEATURE] Laravel Debugbar Logging Middleware

[cheack]

This pull request introduces middleware support for Laravel Debugbar, extending functionality by adding a middleware stack to log queries and measure query execution time.

Example queries:

app('em')->getConnection()->executeQuery("SELECT 'raw query'");
app('em')->getConnection()->executeQuery("SELECT :query", ['query' => 'prepared query']);
app('em')->getConnection()->executeQuery('SELECT pg_sleep(1)');
app('em')->getConnection()->executeQuery('SELECT pg_sleep(2)');
User::pluck('id');

Result:

Usage (doctrine.php config):

'middlewares' => [
    \LaravelDoctrine\ORM\DBAL\Middleware\LaravelDebugbarLogging\Middleware::class
]

I'm going to add the tests later, after one of the reviewers confirms that my changes make sense.

This is the wrong connection, most likely. And for us without Illuminate\Database\Connection in container at all will it crash 😭

Need to subclass this Connection with a "proxy" into the doctrine connection or something 🤔

In fact, there will be a valid connection here, which is specified in the doctrine.managers.default.connection config, which in turn is configured in the database.connections config.
If there is no Illuminate\Database\Connection yet on this step, it will be created with above config.

Sounds to me you have \Illuminate\Database\DatabaseServiceProvider enabled in config/app.php?

I do not, and it would be required for this to work, which seems weird.
