* Create loki client type and ping method
* Expose TestConnection on client
* Configure and ping Loki URL
* Close response body reader if present
* Add 30 second timeout
* Remove duplicate close
This commit adds a customizable timeout for screenshots called
capture_timeout. The default value is 10 seconds, and the maximum
value is 30 seconds. This timeout should be less than the minimum
Interval of all Evaluation Groups to avoid back pressure on alert
rule evaluation.
* Alerting: Add config disabled_labels to disable reserved labels
[unified_alerting.reserved_labels]
disabled_labels
* Replace IsGrafanaFolderDisabled with more generic IsReservedLabelDisabled
* Simplify SchedulerCfg by including UnifiedAlertingSettings
* Alerting: Update default route groupBy to [grafana_folder, alertname]
Default group by for new routes and migrations is now [grafana_folder, alertname]
This PR renames the configuration key enabled to capture. This is needed as we already have a configuration key with the name enabled.
Fixes#50328

This commit adds a pkg/services/screenshot package for taking and uploading screenshots of Grafana dashboards. It supports taking screenshots of both dashboards and individual panels within a dashboard, using the rendering service.
The screenshot package has the following services, most of which can be composed:
BrowserScreenshotService (Takes screenshots with headless Chrome)
CachableScreenshotService (Caches screenshots taken with another service such as BrowserScreenshotService)
NoopScreenshotService (A no-op screenshot service for tests)
SingleFlightScreenshotService (Prevents duplicate screenshots when taking screenshots of the same dashboard or panel in parallel)
ScreenshotUnavailableService (A screenshot service that returns ErrScreenshotsUnavailable)
UploadingScreenshotService (A screenshot service that uploads taken screenshots)
The screenshot package does not support wire dependency injection yet. ngalert constructs its own version of the service. See https://github.com/grafana/grafana/issues/49296
This PR also adds an ImageScreenshotService to ngAlert. This is used to take screenshots with a screenshotservice and then store their location reference for use by alert instances and notifiers.
* update AlertingEnabled and UnifiedAlertingSettings.Enabled to be pointers
* add a pseudo migration to fix the AlertingEnabled and UnifiedAlertingSettings.Enabled if the latter is not defined
* update the default configuration file to make default value for both 'enabled' flags be undefined
Misc
* update Migrator to expose DB engine. This is needed for a ualert migration to access the database while the list of migrations is created.
* add more verbose failure when migrations do not match
