After #6217, internal rgw spawning on external cluster was still broken,
operator claiming:
```
ceph-object-controller: failed to reconcile failed to create object
store deployments: failed to reconcile external endpoint:
failed to create or update object store "arch-cloud" endpoint:
failed to create endpoint "rook-ceph-rgw-arch-cloud". Endpoints
"rook-ceph-rgw-arch-cloud" is invalid: subsets[0]:
Required value: must specify `addresses` or `notReadyAddresses`
```
To spawn internal rgw for external cluster, changes detection of
what mean 'internal' for rgw and only use the externalRgwEndpoints
list for that independently of the status of the cluster
Now there is multiple posibilities:
* internal cluster and internal rgw pods: "normal case"
* external cluster and internal rgw pods: <= now working with the PR
* external cluster and external rgw pods: the external case
* internal cluster and external rgw pods: <= new case that could exist
