http://docs.ansible.com/ansible/latest/playbooks_roles.html#role-dependencies
"Roles dependencies are always executed before the role that includes
them, and are recursive. By default, roles can also only be added as a
dependency once - if another role also lists it as a dependency it will not
be run again. This behavior can be overridden by adding allow_duplicates:
yes to the meta/main.yml file. For example, a role named ‘car’ could add a
role named ‘wheel’ to its dependencies as follows:"
Does 'allow_duplictes: yes' work?"
