What is this feature?
This PR implements a jitter mechanism for periodic alert state storage to distribute database load over time instead of processing all alert instances simultaneously. When enabled via the state_periodic_save_jitter_enabled configuration option, the system spreads batch write operations across 85% of the save interval window, preventing database load spikes in high-cardinality alerting environments.
Why do we need this feature?
In production environments with high alert cardinality, the current periodic batch storage can cause database performance issues by processing all alert instances simultaneously at fixed intervals. Even when using periodic batch storage to improve performance, concentrating all database operations at a single point in time can overwhelm database resources, especially in resource-constrained environments.
Rather than performing all INSERT operations at once during the periodic save, distributing these operations across the time window until the next save cycle can maintain more stable service operation within limited database resources. This approach prevents resource saturation by spreading the database load over the available time interval, allowing the system to operate more gracefully within existing resource constraints.
For example, with 200,000 alert instances using a 5-minute interval and 4,000 batch size, instead of executing 50 batch operations simultaneously, the jitter mechanism distributes these operations across approximately 4.25 minutes (85% of 5 minutes), with each batch executed roughly every 5.2 seconds.
This PR provides system-level protection against such load spikes by distributing operations across time, reducing peak resource usage while maintaining the benefits of periodic batch storage. The jitter mechanism is particularly valuable in resource-constrained environments where maintaining consistent database performance is more critical than precise timing of state updates.

**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)_ |
Adds a new "Allow as recording rules target" toggle to Prometheus datasource configuration that controls whether the datasource can be selected as a target for writing recording rules.
