feat: restart the host (reboot_host)

netOrk asks a driver for reboot_host before it offers a restart, and the
Linux driver had none, so a Linux host -- and OpenMediaVault and QTS, which
inherit this driver -- could not be restarted from netOrk at all (netOrk
#637). reboot_host runs /sbin/reboot detached and two seconds late through
_run_privileged: the launcher's exit status comes back before the host goes
down, and closing the session cannot take the restart with it. A refusal
(sudo without a password) raises with what the host said.

 For full functionality it is recommended to run as `root` or grant passwordless `sudo` for
 the above commands.
 
+`get_services()` and `manage_service()` come from napalm-device-types'
+`SystemdServicesMixin`; this driver supplies only the transport. An action runs as
+`timeout 45 systemctl --no-ask-password <action> -- <unit>.service`, so a unit that hangs
+on its way up or down cannot hold the session, and only the exit status decides whether it
+succeeded. Without a sudo password it uses `sudo -n`, which fails at once instead of
+waiting for a password prompt.
+
+On OpenMediaVault (napalm-openmediavault inherits this driver), enabling or disabling a
+unit that OMV manages itself — Samba, NFS, SSH — may be reverted the next time OMV applies
+its configuration.
