Prior to this change it was not possible to generate the config
before deploying the services as you'd hit:
RUNNING HANDLER [Waiting for grafana to start on first node] *************************
Monday 18 January 2021 15:06:35 +0000 (0:00:00.182) 0:04:39.213 ********
skipping: [sv-h22a8-u19]
skipping: [sv-h22a5-u36]
FAILED - RETRYING: Waiting for grafana to start on first node (10 retries left).
This would never succeed as the service has not yet been deployed.
TrivialFix
