This allows you to print out which tasks will be executed, without actually running the tasks. It could help debug using the tag and filtering features. When developing, it makes the feedback loop quicker because non of the tasks need to execute. Note this doesn't work for kolla-ansible, as their CLI doesn't support this command line. Which frankly makes this a little useless, but we could always push that upstream if it proves handy.
