Have zuul-cloner install ansible-roles

For example, zuul-cloner will install ansible-role-nodepool into
playbooks/roles/windmill.nodepool.  This naming format is inline with
how roles installed from ansible galaxy.

The reason we use zuul-cloner, is it gives us the ability to gate on
cross repo changes. Rather then always installing from master.
