We introduced a new Ansible role, tripleo-bootstrap:
I560273be2ebe3a49ff37e3682222706939e5d879
This role will take care of preparing an environment that will deploy
TripleO later.
This patch aims to use execute this new role on all hosts.
We don't gather_facts, (already gathered previously), we want to fail on
any error and also the role will be executed on pre_deploy_steps tag.
