I chose not to use any * shortenings, as we've been burnt by picking up unexpected systemd units before.

You probably want to remove the haproxy configuration and restart the haproxy container first, then stop/delete the heat containers.

More is needed to be thorough. Remove Heat configuration generated by Kolla:

kayobe overcloud host command run --command "rm -rf /etc/kolla/heat-api /etc/kolla/heat-api-cfn /etc/kolla/heat-engine " --limit controllers -b

Remove the Heat service, endpoints (done automatically on service removal), user and domain. From an OpenStack virtual environment:

openstack service delete heat
openstack user delete heat
openstack domain set --disable heat_user_domain
openstack domain delete heat_user_domain

You can drop the database too, unless you want to keep historical content.

Thanks @priteau, I was hoping for someone to spot anything I'd missed :)
