fix: restart qdevice when its certificates have been regenerated

[tomjelinek]

Enhancement:
Always restart qdevice daemon on cluster nodes when certificates for qdevice - qnetd communication have changed.

Reason:
With the restart missing, qdevice and qnetd were not able to communicate in certain scenarios. This basically rendered qdevice not working until the cluster is restarted.

Result:
Communication between qdevice (cluster nodes) and qnetd (quorum device) works.
