This is cross-package issue for public packages.

We need to make sure php-cs-fixer configuration is updated according to rules introduced in v2.7.1 as this is what we use now for CI.

While handling this, it's worth to:

• explore a possibility of making require-dev dependency on friendsofphp/php-cs-fixer:~2.7.1 so developers can know which version to align with.
• if the above succeeds, then add composer fix-cs command to simplify fixing code even more

Note that this might not be possible due to symfony/console <3.2 constraints in some packages, however if it works, proper solution is already known and identical for all packages.

List of affected public packages:

• ezsystems/comments-bundle
• ezsystems/content-on-the-fly-prototype
• ezsystems/ezplatform-design-engine
• ezsystems/ezplatform-http-cache (no .php_cs yet, might require more work)
• ezsystems/ezplatform-multi-file-upload
• ezsystems/ezplatform-solr-search-engine
• ezsystems/ezpublish-kernel
• ezsystems/ez-support-tools (no .php_cs yet, might require more work)
• ezsystems/platform-ui-bundle
• ezsystems/recommendation-bundle
• ezsystems/repository-forms
• ezsystems/share-buttons-bundle
• ezsystems/ezplatform-admin-ui

Note that for some repositories the changes were already made.
