This removes osbs and allmost all it's associated playbooks and files.
It served long and well, but we no longer need it.
flatpaks are building with a koji-flatpak plugin.
base/minimal/toolbox containers are building with kiwi.
We aren't building any other containers right now, and we did they could
be added to kiwi.
This is the end of an era... I look with nostolga on
ansible-ansible-openshift-ansible (a role to setup ansible on a control
host and run it from our ansible).
Good bye osbs!
