[buskamuza]

Update friendsofphp/php-cs-fixer (https://github.com/FriendsOfPHP/PHP-CS-Fixer) to the version that supports PHP 7.2. Install latest version of friendsofphp/php-cs-fixer

AC:

• tests are green
• usage scenarios are working

It also requires update of symfony/console, symfony/process and symfony/event-dispatcher to a newer versions. Please update to the latest possible.

As previously mentioned this will require an update of symfony/console to at least v3.2.0. symfony/console is currently restricted to ~2.3, !=2.7.0 by:

• magento/magento2ce
• magento/composer
• sjparkinson/static-review (abandoned)
