Patching scheduler0.staging, it's ok with that new setup:
```
root@scheduler0:~# date
Mon 30 Aug 2021 10:17:20 AM UTC
root@scheduler0:~# systemctl status swh-scheduler-update-metrics.timer | grep -i trigger
Trigger: Mon 2021-08-30 12:00:00 UTC; 1h 42min left
Triggers: ● swh-scheduler-update-metrics.service
