[5.5] Adds task command output to Artisan commands

[nunomaduro]

This PR addresses a creation of new command output. Adding a new method to the Artisan Illuminate\Console\Command class that allows the an user to understand the result of the given task.

• The task method code

    /**
     * Write a string as task output.
     *
     * @param  string  $string
     * @param  callable  $callable
     * @return void
     */
    public function task($string, callable $callable)
    {
        $result = $callable() ? '<info>✔</info>' : '<error>fail</error>';

        $this->output->writeln("$string: $result");
    }

• Usage example

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        $this->task('Downloading Laravel', function () {
            $response = Client::download('cabinet.laravel.com/latest.zip', storage_path('latest.zip'))

            return response->success();
        });
    }

• Result

This should be in your own extending class IMO.

I do kind of like it but also agree that probably we should leave it up to the developer to add this helper to their own class. Thanks!

Pretty cool, indeed.

Is the command macroable to allow this method to get added? And if not - is that more of a solution to enable this functionality for people?

[nunomaduro]

@OwenMelbz I may create a package for this. I keep you posted 🙂

@OwenMelbz @m1guelpf Just created a package with this feature: https://github.com/nunomaduro/laravel-console-task

@nunomaduro maybe you could even look at how spatie implemented the parallelMap in order to try parallel task.
