[pbs-devel] [PATCH v2 proxmox-backup] api2/node/services: Handle optional services and expose unit-state

[Christoph Heiss]

.. in the same way the PVE api does, esp. regarding the logic to handle
oneshot and missing services.

This then allows re-using the GUI parts from there as well, so that the
services page in PVE and PBS looks the same.
