* Alerting: Keep state manager cache during cache warm-up

Instead of overwriting the state manager cache during warm-up,
we update the data in the cache if it is not there yet. If the cache
already contains a state entry with the same key, we do not overwrite it.

Alexander Akhmetov 2035814059 Alerting: fix updating error in the alert rule state during error to error transitions and restarts (#89557)
Alerting: fix preserving errors in the alert rule state during error to error transitions

Alert state transition from one error to another did not update state.Error correctly.
The error in state.Error remained as the initial error encountered.
This led to another issue, where after a Grafana restart, the error was lost because
the state of the alert rule did not change, but the Error is not preserved in the database
between restarts.

This could happen if the expression service returned an error or the alert routine panicked
during querying.

Matthew Jacobson 3228b64fe6 Alerting: Resend resolved notifications for ResolvedRetention duration (#88938)
* Simple replace of State.Resolved with State.ResolvedAt

* Retain ResolvedAt time between Normal->Normal transition

* Introduce ResolvedRetention to keep sending recently resolved alerts

* Make ResolvedRetention configurable with resolved_alert_retention

* Tick-based LastSentAt for testing of ResendDelay and ResolvedRetention

* Do not reset ResolvedAt during Normal->Pending transition

Initially this was done to be inline with Prom ruler. However, Prom ruler
doesn't keep track of Inactive->Pending/Alerting using the same alert instance,
so it's more understandable that they choose not to retain ResolvedAt. In our
case, since we use the same cached instance to represent the transition, it
makes more sense to retain it.

This should help alleviate some odd situations where temporarily entering
Pending will stop future resolved notifications that would have happened
because of ResolvedRetention.

* Pointers for ResolvedAt & LastSentAt

To avoid awkward time.Time{}.Unix() defaults on persist
