Install update-metrics as a service called daily

Antoine R. Dumont requested to merge generated-differential-D6052-source into generated-differential-D6052-target

As an implementation detail, the service is called daily through a systemd timer.

This updates the scheduler_metrics table regularly so the distribution per forge stays up-to-date. This also avoid having this running in a tmux session on saatchi. This also deals with properly update such metrics on the staging infra.

Test Plan

tests within vagrant as well:

root@scheduler0:~# systemctl status swh-scheduler-update-metrics.timer
● swh-scheduler-update-metrics.timer - regular scheduler update-metrics refresh
   Loaded: loaded (/etc/systemd/system/swh-scheduler-update-metrics.timer; enabled; vendor preset: enabled)
   Active: active (waiting) since Tue 2021-08-03 14:29:18 UTC; 1min 6s ago
  Trigger: Wed 2021-08-04 00:00:00 UTC; 9h left

octo diff on scheduler nodes, this wants to install the timer and service (only scheduler0.staging, same goes for saatchi):
