#5691 "Generic Prometheus dashboard widget: pick a target and a template",
step 3 of milestone 508 "Prometheus widget templates".
- /plugins/prometheus/widget draws one target with one template in widget
shape: the verdict (led by "isn't answering" when the target is down),
then each block with problems first, figures beside a share bar or the
last 24h of bars, and the healthy rest folding to "+N more healthy" past
six. A missing target or template, or one that no longer checks, says so.
- library.py: bundled templates from plugins/prometheus/widgets/*.yaml,
the picker's target and template lists, and the default title.
- widgets/fabled_archives.yaml: the first bundled template, against the
series Archives reports (refined in #5693).
- Dashboard: a widget setting may take `options_from` (read when the picker
opens) with an `empty` sentence; `default_title`; a Details link may name
settings ("/plugins/prometheus/targets/{target}"). Prometheus is grouped
with the integrations.
