[PATCH 5/7] client: job: ship systemd user unit for the scheduler

[Thomas Lamprecht <t.lamprecht@proxmox.com>]

Not enabled on install, as a backup daemon only makes sense for users
who configured a job. KillMode=mixed lets a stop wait for running
backups, and restarts give up if startup keeps failing, for example
because a scheduler already runs in a terminal.
