Allow console command specific extra options.

Add an additional parameter with which you can add console command specific parameters e.g. for console command cleanup versions or check url

• for ezplatform:check-urls the option "--quiet"
• for ezplatform:content:cleanup-versions the options "--keep --status=draft"

Currently you are not able to add this options in the cron config.

The config for cleanup versions cronjob would look like this:

 ezplatform.cron.cleanup_version:
        class: eZ\Bundle\EzPublishCoreBundle\Command\CleanupVersionsCommand
        tags:
            - { name: console.command }
            - { name: ezplatform.cron.job, schedule: '55 23 3 1-12 *', category: 'monthly', options: '--keep=0 --status=draft' }
