"role_name" has been an internal Ansible variable since 2.2 but we use it in TripleO for our own TripleO roles (nothing to do with Ansible roles).

It was working by accident but with Ansible 2.5 it's not seriously considered.
Therefore, some tasks (deploy_step_tasks and probably more) are now ignored when role_name is used in "when" statement.

We need to rename our tripleo role_name variable into triple_role_name to avoid any collision.
