We have access to manage the linaro cloud, but we don't want to
completely own the host as it has been configured with kolla-ansible;
so we don't want to take over things like name resolution, iptables
rules, docker installation, etc.
But we would like to manage some parts of it, like rolling out our
root users, some cron jobs, etc. While we could just log in and do
these things, it doesn't feel very openinfra.
This allows us to have a group "unmanaged" that skips the base jobs.
The base playbook is updated to skip these hosts.
For now, we add a cloud-linaro prod job that just does nothing so we
can validate the whole thing. When it's working, I plan to add a few
things as discussed above.
