Add non-voting jobs for ARA to test the devel branch of Ansible

The Ansible devel branch is working towards the release of Ansible
2.4 and have begun introducing backwards-incompatible changes that
break ARA, such as this one [1].

By having a non-voting job against devel, we are able to see these
changes coming as they land as well as work to resolve the issues
on a continuous basis so that when 2.4 releases, ARA is ready.
