* Alerting: During legacy migration reduce the number of created silences During legacy migration every migrated rule was given a label rule_uid=<uid>. This was used to silence DatasourceError/DatasourceNoData alerts for migrated rules that had either ExecutionErrorState/NoDataState set to keep_state, respectively. This could potentially create a large amount of silences and a high cardinality label. Both of these scenarios have poor outcomes for CPU load and latency in unified alerting. Instead, this change creates one label per ExecutionErrorState/NoDataState when they are set to keep_state as well as two silence rules, if rules with said labels were created during migration. These silence rules are: - __legacy_silence_error_keep_state__ = true - __legacy_silence_nodata_keep_state__ = true This will drastically reduce the number of created silence rules in most cases as well as not create the potentially high cardinality label `rule_uid`.
