Add a Grafana dashboard for the resolver's metrics

Browse Source

With traffic charts gone from the console, deploy/grafana/fancy-dns.json is
where they live: queries by outcome, transport and client group, latency
quantiles, RCODEs, cache hits/misses/stale, the upstream round trips saved by
coalescing and early refresh, upstream health and latency, blocklist and zone
sizes, and (in a Loki row) the blocked/failed-query access log. A node variable
spreads or narrows every panel, and the per-node panel shows whether load is
even across pods.

A test reads the dashboard and fails if a panel queries a metric the resolver
does not export, so a rename cannot silently empty a panel.

The ingress no longer needs the SSE buffering/timeout annotations, and the
statefulset comments no longer describe a query log on the volume.
