Goal: 

As a user and administrator of BRQ2 cluster, I want to add and remove EDPM nodes, upgrade RHOSO versions, reconfigure control and dataplane depending on work in progress (testing/benchmarking/verification, building reference architectures, etc.), where the source configuration is derived from some VA or DT, then adapted for our hardware and lab specifics.

And I want to be as close to what customers would do for the similar tasks, as possible.

Acceptance Criteria:

• No extra tooling, which is not customers faced, like ci-framework or ci-framework-jobs should be used. Just kustomize and oc (secrets management is an open question though).
• Hardware (EDPM hosts) addition, removal, reconfiguration and replacement scenarios can be executed in a few simple steps (kustomize, oc, openstack client) for existing RHOSO deployment on BRQ2 cluster.
• We can switch the base reference DT or VA as we need, and apply our configuration layer on top without rebuilding this repository structure

Out of scope yet:

• Making this gitops repo a fully compatible with the gitops system of a choice (like ArgoCD) and secrets management of a choice (like Vault)
• Deploying/reconfiguring OCP clusters
