Subject: [PATCH] prometheus: use inovex/prometheus-libvirt-exporter

The Tinkoff/libvirt-exporter is archived. Latest release in December
2022. The inovex/prometheus-libvirt-exporter is an active fork that will
most probably become a prometheus community exporter in the future [1].

Unfortunately this exporter is not 100% compatible with Tinkoff exporter
that we are using currently [2].

[2]: https://github.com/inovex/prometheus-libvirt-exporter/issues/22
