[P1BIGROCKS-1775](https://jira.il2.dso.mil/browse/P1BIGROCKS-1775) BigBang provides capabilities to platform teams, but also should provide capabilities to Tenants on the platform as well. For instance, MinIO operators, Postgres/MySQL Databases, etc. As part of this epic, we need to look at the security implications of how Tenants can use Big Bang `GitRepositories` and `HelmReleases`/`Kustomizations`. https://github.com/fluxcd/flux2-multi-tenancy - [ ] Force Tenant `HelmRelease` and `Kustomizations` to have a local service account - [ ] Only allow that service account permissions to its own namespace via OPA policy - [ ] Allow tenants to create `GitRepositories`, `HelmRelease` and `Kustomization` objects
