[5.6] Passing parameters to Grouped Middleware(s) on Routes middleware setup

[isocroft]

Okay, so i work for @synergixe and we had some problem reference by issue #24668 and we had to use a workaround (please see workaround code in issue referenced) which my company posted on that issue. This is a pull request that makes it easier to do the below and have all group middlewares receive the same parameters automatically.

     /* example middleware */
     namespace App\Cors;

     use \Barryvdh\Cors\HandleCors;

    class OpsCors extends HandleCors {

    }

        /* app/Http/Kernel.php */

            protected $middlewareGroups =  [
                   'security' => [
                         \App\Http\Middleware\LogStuff::class,
                         \App\Cors\OpsCors::class
                   ]
           ];

      /* routes/web.php */

     Route::middleware(['security:web'])->group(function(){
             Route::get('/model/{model_test}/', function(App\ModelTest $model_test){
                   return $model_test->getAttributes();
             });
     });

This will make the life of an average Laravel developer a lot easier going forward. Thanks

Nice work @isocroft

[GrahamCampbell]

Thanks for the PR. Any chance you could add some tests so that it's clear what the code does to future readers, and to ensure it doesn't get broken in the future?

No plans to add this right now. Code is kinda gnarly.

@GrahamCampbell I'll be sure to add tests to the PR for proper scrutiny ASAP. Perhaps, I and @taylorotwell could work on this later on with a less challenging context to it. Cheers
