rgw: raise errors when rgw daemon fails to be created

The generation of the rgw deployment spec was swallowing errors
if any issues are raised such as the tls cert not being found
as expected in some configurations. We need to fail the reconcile
so the error will be logged and the admin can identify the issue.
