Backend:
* Update the Grafana Alerting engine to provide feedback to HysteresisCommand. The feedback information is stored in state.Manager as a fingerprint of each state. The fingerprint is persisted to the database. Only fingerprints that belong to Pending and Alerting states are considered as "loaded" and provided back to the command.
- add ResultFingerprint to state.State. It's different from other fingerprints we store in the state because it is calculated from the result labels.
- add rule_fingerprint column to alert_instance
- update alerting evaluator to accept AlertingResultsReader via context, and update scheduler to provide it.
- add AlertingResultsFromRuleState that implements the new interface in eval package
- update getExprRequest to patch the hysteresis command.
* Only one "Recovery Threshold" query is allowed to be used in the alert rule and it must be the Condition.
Frontend:
* Add hysteresis option to Threshold in UI. It's called "Recovery Threshold"
* Add test for getUnloadEvaluatorTypeFromCondition
* Hide hysteresis in panel expressions
* Refactor isInvalid and add test for it
* Remove unnecesary React.memo
* Add tests for updateEvaluatorConditions

* Alerting: Attempt to retry retryable errors
Retrying has been broken for a good while now (at least since version 9.4) - this change attempts to re-introduce them in their simplest and safest form possible.
I first introduced #79095 to make sure we don't disrupt or put additional load on our customer's data sources with this change in a patch release. Paired with this change, retries can now work as expected.
There's two small differences between how retries work now and how they used to work in legacy alerting.
Retries only occur for valid alert definitions - if we suspect that that error comes from a malformed alert definition we skip retrying.
We have added a constant backoff of 1s in between retries.

* Alerting: Attempt to retry retryable errors
Currently in a draft state, but this was the minimal diff I could put together to exemplify how could achieve this.

This commit fixes a bug where DatasourceUID and RefID annotations are
missing for DatasourceNoData alerts in Grafana 9.5. This bug affects
datasource plugins that have moved to using the data plane contract.
Takes a specific code path for data that identifies itself as dataplane instead of "guessing" what the data is.
The data must identify itself by being in the dataplane by having both the following frame metadata properties:
- TypeVersion property that is greater than 0.0
- 'Type' property
The flag is disableSSEDataplane and disables this functionality and uses the old code for all queries regardless.
See https://github.com/grafana/grafana-plugin-sdk-go/blob/main/data/contract_docs/contract.md for dataplane details.
* Alerting: Tiny refactor on the eval and schedule packages
two very small things:
- We had a constructor on something called a `Context` which is not a `context.Context` so let's just name that constructor `NewContext`
- The user that we use to run query evaluations is the same (with some variation) abstract it to a function so that it can be re-used when necessary.
* Update pkg/services/ngalert/schedule/schedule.go

* Extract header logic and add rule UID header
* Fix missing call
This commit is one of two commits to make the data frames for all queries and expressions in an alert rule available to the state package for rendering a graph. It renames Result to Condition, and creates an additional field called
Results that is a map of Ref ID to data.Frames.
