Jean-Philippe Evrard e0ef9e384a Make possible to use ansible 2.4 ... Ansible 2.4 has changed the interface for var plugins. Our vars plugin shouldn't be used in ansible 2.4, because the features we were looking for are now standard. However the plugin is still shipped. So we need to ensure this vars plugin doesn't get loaded on ansible 2.4. Ansible will not load a vars plugin in its plugin location if no VarsModule is defined. This commit abuses this mechanism to conditionally load the vars module depending on the version, at the expense of throwing a warning in Ansible 2.4. This is backported to fix an upgrade bug: While ansible 2.3 shouldn't have an issue loading the plugin, upgrading to Queens would, if the ANSIBLE_ROLE_FETCH_MODE=git-clone is used, temporarily use ansible to get new roles, including plugins. That would temporarily load the previous roles with a new version, and cause failure.
