For now, we have implemented two different approaches in test-infra project.
ONE summit approach (Enabled) - Deploys a 'static' management and workload infrastructure with Ansible playbooks created in the ONE summit repo. This approach has been tested, but eventually will be deprecated.
Cluster API approach (Disabled) - Deploys the management cluster only and workloads will be requested as Cluster API CRs. There is work on progress on this approach.
