Replace cronjobs with systemd timers Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/756 Related to https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/737 I feel like timers are somewhat more complicated and dirty (compared to cronjobs), but they come with these benefits: - log output goes to journald - on newer systemd distros, you can see when the timer fired, when it will fire, etc. - we don't need to rely on cron (reducing our dependencies to just systemd + Docker) Cronjobs work well, but it's one more dependency that needs to be installed. We were even asking people to install it manually (in `docs/prerequisites.md`), which could have gone unnoticed. Once in a while someone says "my SSL certificates didn't renew" and it's likely because they forgot to install a cron daemon. Switching to systemd timers means that installation is simpler and more unified.
