This adds a grafana02 server to our inventory with associated LE host
vars. This should deploy grafana on our newly created noble grafana02
server.
Note we switch the system-config-run-grafana job over to interact with
02 to match production. To simplify this effort in the future we convert
the old grafana01 testing host var to a group var file. This change was
already done on bridge.
We will need to followup with at least one change to clean out grafana01
when we are happy with the new server.
