clusterctl in a GitOps way.

Going to park this, most likely permanently.

• CAPI (and providers) do not provide helm charts or package management. Extracting manifests is hacky (patching env vars by manipulating yaml file), realease upgrades come with no guarantee (will have to download new manifests, compare and watch for potential changes)
• CAPA manifests have AWS credentials as part of the manifest. They could be zeroed out in favor of IRSA, but this has some complications. There is no IRSA on kind cluster, nor in plain AWS clusters that this project is currently working with. Even if swapping out IRSA for kiam (which is now deprecated due to prevalence of EKS and IRSA) I would still have to commit ARNs of the roles that contain AWS account ID (even though it is not strictly sensitive I prefer to avoid this).
• There is a lot of work in the area of the project that least interests me. Especially given the fact that the current installation and tear down way work perfectly fine (even though not very pretty and 100% written in bash). There is more value in improving this process by removing CRS in favor of (not yet released) CAPI Helm Provider.
