Arvados

arvados-login-sync expects to run as a cron job (install guide recommends running every 2 minutes). Suggest using a systemd timer file for this.

Long term it will make more sense for login-sync to listen for relevant events on websocket and sync whenever keys/users/groups change. If the timer behavior is done with systemd instead of cron, when the time comes it should be easy to switch to a long-running service model just by upgrading the package, without manual intervention.
