Alexander Akhmetov	ad683f83ff	Alerting: Add state history backend to write ALERTS metric (#104361) ... **What is this feature?** This PR implements a new Prometheus historian backend that allows Grafana alerting to write alert state history as Prometheus-compatible `ALERTS` metrics to remote Prometheus-compatible data sources. The metric includes a few additional labels: * `grafana_alertstate`: Grafana's full alert state, more granular than Prometheus. * `grafana_rule_uid`: Grafana's alert rule UID. Grafana states are included in the `grafana_alertstate` label also mapped to Prometheus-compatible `alertstate` values: | Grafana alert state | `alertstate` | `grafana_alertstate` | |---------------------|-----------------------|-----------------------| | `Alerting` | `firing` | `alerting` | | `Recovering` | `firing` | `recovering` | | `Pending` | `pending` | `pending` | | `Error` | `firing` | `error` | | `NoData` | `firing` | `nodata` | | `Normal` | _(no metric emitted)_ | _(no metric emitted)_ |	1 month ago
