knotd still fails to start if it can't load certificates or keys. This
appears to be a bug given that "knotd: server crashes when it fails to
load a QUIC/TLS key" is in the release notes for knot-dns v3.5.6.
Below is a patch that allows the server to start if knotd can't load the
certificates/keys.

grafana 13.0.2
i am running the [python version](https://gitlab.nic.cz/knot/knot-dns/-/tree/master/python/knot_exporter)
of knot_exporter on the dns server
.../knot-exporter --web-listen-addr 666.42.7.11 --web-listen-port 9443
prometheus on my webby host seems to be pulling happily from 9443 of the
knotty server. i.e. http://knotty.host:9443/metrics has a lot of data
and http://webby.host:9090/metrics has data
and grafana drilldown/metrics has pretty data
but which main grafana dashboard json should i be using for knot?
https://grafana.com/grafana/dashboards/14989-knot-metrics-dashboard/
displays a lot of No Data
