Alerting: Support hysteresis command expression (#75189)

Browse Source 
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
