Update grafana /api/auth/keys to /api/serviceaccounts on the Grafana integration job
Currently, The StackGres operator uses the grafana API /api/auth/keys to integrate grafana dashboards in the UI. This endpoint will be deprecated in future grafana releases.
This needs to be changed to /api/serviceaccounts
You can find the documentation about the change here https://grafana.com/docs/grafana/latest/administration/api-keys/#migrate-api-keys-to-grafana-service-accounts-for-api-calls
Acceptance Criteria
- The Grafana integration no longer uses the deprecated API endpoint
