This patch adds a timeout to notice a failure, when the container hangs and does not do anything. This happened already and with moving the mount and unmount and snapshot management to the service file, we ensure that they are properly removed after a timeout. Thanks to @Histalek for the service config (https://git.histalek.de/histalek-de/infrastructure/-/blob/main/roles/lvm_backup/templates/backup-lvm.service)
