The building of the group "repo_masters" relies on going through the inventory, but we never check if the hosts are added in a particular order. While it should follow the ansible inventory order (that's the play order by default), the inclusion of the host to a group could happen at any time, because the play runs all the hosts in parallel. If we ensure the hosts are run serially, the addition of the hosts to the architecture dependant repo_ groups will always be done in the right order. We can then use these groups to find which host is the first one, and use it as "repo_master". Change-Id: I51803dab20e85bd6c100821ce5c1c1ad3226ba29
