Initial support for alerting with SQL expressions - When `format` is set to `alerting`, SQL expressions output in a format suitable for alerting evaluation. - Outstanding TODOs: - Deduplicate output rows - Add more tests - Fix broken alerting UI rendering (likely due to shape change to undocumented full-long format) - Basic usage: - SQL must return one numeric column and one or more string columns. - Each row may become an alert. - The alert fires if the numeric value is non-zero. - String columns are treated as labels. --------- Co-authored-by: Konrad Lalik <konradlalik@gmail.com> Co-authored-by: Tom Ratcliffe <tom.ratcliffe@grafana.com> Co-authored-by: Sam Jewell <sam.jewell@grafana.com>
