* Alerting: Add setting for maximum allowed rule evaluation results
Added a new configuration setting `quota.alerting_rule_evaluation_results` to set the maximum number of alert rule evaluation results per rule. If the limit is exceeded, the evaluation will result in an error.
* expose ngalert API to public
* add delete action to time-intervals
* introduce time-interval model generated by app-platform-sdk from CUE model the fields of the model are chosen to be compatible with the current model
* implement api server
* add feature flag alertingApiServer
---- Test Infra
* update helper to support creating custom users with enterprise permissions
* add generator for Interval model
This adds a version of the SQLStore that includes a ReadReplica. The primary DB can be accessed directly - from the caller's standpoint, there is no difference between the SQLStore and ReplStore unless they wish to explicitly call the ReadReplica() and use that for the DB sessions.
Currently only the stats service GetSystemStats and GetAdminStats are using the ReadReplica(); if it's misconfigured or if the databaseReadReplica feature flag is not turned on, it will fall back to the usual (SQLStore) behavior.
Testing requires a database and read replica - the replication should already be configured. I have been testing this locally with a docker mysql setup (https://medium.com/@vbabak/docker-mysql-master-slave-replication-setup-2ff553fceef2) and the following config:
[feature_toggles]
databaseReadReplica = true
[database]
type = mysql
name = grafana
user = grafana
password = password
host = 127.0.0.1:3306
[database_replica]
type = mysql
name = grafana
user = grafana
password = password
host = 127.0.0.1:3307
