* SSE: DSNode to update result with names to make each value identifiable by labels (only Graphite and TestData) (#71246)
* introduce a function checkIfSeriesNeedToBeFixed to scan all value fields in the response and provide a function that updates Series so they can be uniquely identifiable. Only Graphite and TestData are checked.
* update `DSNode.Execute` to run this function and provide it to WideToMany
* update WideToMany to run the fix function if it is not nil
* Alerting: Support concurrent queries for saving alert instances (#70525)
This commit adds support for concurrent queries when saving alert
instances to the database. This is an experimental feature in
response to some customers experiencing delays between rule evaluation
and sending alerts to Alertmanager, resulting in flapping. It is
disabled by default.
