feat: backstage manifests using single namespace

Instead of using backstage in other namespace, just don't use, this will
allow  to deploy multiple instances in different namespaces:

Like:
```
kubectl kustomize hack/manifests/backstage/ | kubectl apply -n differentOne -f -
```

Or in default:

```
kubectl kustomize hack/manifests/backstage/ | kubectl apply -n default -f -
```

Fix FLPATH-511
