Joe Blubaugh 9e8efaa459 Alerting: Add stored screenshot utilities to the channels package. (#49470)
Adds three functions:
`withStoredImages` iterates over a list of models.Alerts, extracting a stored image's data from storage, if available, and executing a user-provided function.
`withStoredImage` does this for an image attached to a specific alert.
`openImage` finds and opens an image file on disk.

Moves `store.Image` to `models.Image`
Simplifies `channels.ImageStore` interface and updates notifiers that use it to use the simpler methods.
Updates all pkg/alert/notifier/channels to use withStoredImage routines.

Joe Blubaugh 1cc034d960 Alerting: Add a "Reason" to Alert Instances to show underlying cause of state. (#49259)
This change adds a field to state.State and models.AlertInstance
that indicate the "Reason" that an instance has its current state. This
helps us account for cases where the state is "Normal" but the
underlying evaluation returned "NoData" or "Error", for example.

Fixes #42606

Joe Blubaugh 687e79538b Alerting: Add a general screenshot service and alerting-specific image service. (#49293)
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.

Kristin Laemmert 1df340ff28 backend/services: Move GetDashboard from sqlstore to dashboard service (#48971)
* rename folder to match package name
* backend/sqlstore: move GetDashboard into DashboardService

This is a stepping-stone commit which copies the GetDashboard function - which lets us remove the sqlstore from the interfaces in dashboards - without changing any other callers.
* checkpoint: moving GetDashboard calls into dashboard service
* finish refactoring api tests for dashboardService.GetDashboard

Joe Blubaugh 3d91047e6e Alerting: Notification URL points to alert view page instead of alert edit page (#47752)
Before this change, notifications generated by the Grafana Alertmanager
pointed to '/alerting/:ruleID/edit'. This change instead points them to
the view path '/alerting/grafana/:ruleID/view'. The view page has a
better UX, including timeseries display. It's also where many alert
state improvements will land in the next few versions of Grafana.

Fixes #45301

Yuriy Tseretyan ed5c664e4a Alerting: Stop firing of alert when it is updated (#39975)
* Update API to call the scheduler to remove\update an alert rule. When a rule is updated by a user, the scheduler will remove the currently firing alert instances and clean up the state cache. 
* Update evaluation loop in the scheduler to support one more channel that is used to communicate updates to it.
* Improved rule deletion from the internal registry. 
* Move alert rule version from the internal registry (structure alertRuleInfo) closer rule evaluation loop (to evaluation task structure), which will make the registry values immutable.
* Extract notification code to a separate function to reuse in update flow.
