SQLite install tasks requires the file_system service

Problem/Motivation

When installing with a Drupal site which has it's database connection predefined for SQLite (and maybe without), the Drupal site crashes due to the file_system service not being available

<br />
<b>Fatal error</b>:  Uncaught Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service &quot;file_system&quot;. in /persist/drupal/vendor/symfony/dependency-injection/ContainerBuilder.php:992

The minimal container created in install_begin_request doesn't setup the service before invoking install_verify_database_settings

Steps to reproduce

Try to install Drupal with an existing sites/default/settings.php that contains

$databases['default']['default'] = array (
  'database' => 'sites/default/files/.sqlite',
  'prefix' => '',
  'driver' => 'sqlite',
  'namespace' => 'Drupal\\sqlite\\Driver\\Database\\sqlite',
  'autoload' => 'core/modules/sqlite/src/Driver/Database/sqlite/',
);

Proposed resolution

Register file_system

Remaining tasks

User interface changes

Introduced terminology

API changes

Data model changes
