PRI-750: update plugin repos to reference shared infra RBAC (PRI-695 follow-up)
- deployment/e2e-ci-runner-rbac.yaml: replaced duplicate manifest with
reference comment pointing to privilegedescalation/infra/base/rbac/e2e-ci-runner-headlamp-rbac.yaml
- scripts/deploy-e2e-headlamp.sh: updated RBAC preflight comment and error
message to reference infra path
- scripts/teardown-e2e-headlamp.sh: added RBAC reference comment
Infra RBAC is the source of truth managed by Flux GitOps. CI workflow
unchanged (Hugh owns .github/workflows/).
headlamp-dev is Flux-managed (kustomization/headlamp-dev reconciles), causing
E2E deployment conflicts and test failures. Use a dedicated headlamp-plugins-e2e
namespace instead. Reverted .github/workflows/e2e.yaml — Hugh owns CI/CD; will
file a child issue to update the workflow namespace.
