* 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.
* Allow customizable googlechat message via optional setting
* Add optional message field in googlechat contact point configurator
* Fix strange error message on send if template fails to fully evaluate
* Elevate template evaluation failure logs to Warn level
* Extract default.title template embed from all channels to shared constant
* Create API test for overwriting invalid alertmanager config
* Avoid requiring alertmanager readiness for config changes
* AlertmanagerSrv depends on functionality rather than concrete types
* Add test for non-ready alertmanagers
* Additional cleanup and polish
* Back out previous integration test changes
* Refactor of tests incorrectly caused a test to become redundant
* Use pre-existing fake secret service
* Drop unused interface
* Test against concrete MultiOrgAlertmanager re-using fake infra from other tests
* Fix linter error
* Empty commit to rerun checks
* change registry.delete to return deleted struct
* use pointer to alertRuleInfo instead copying.
* do not access evaluation channel when routine is stopped
* remove stopCh and use context cancellation
* do not return ctx.Err when channel is cancelled because it cancels all other routines
* make alertRuleInfo fields and functions package private
* refactor datasource loading
* refactor datasource loading
* pass uid
* use dscache in alerting to get DS
* remove expr/translate pacakge
* remove dup injection entry
* fix DS type on metrics endpoint, remove SQL DS lookup inside SSE
* update test and adapter
* comment fix
* Make eval run as admin when getting datasource info

* Fix flaky tests in several notifiers
- Non-mocked time in sensu go tests
- Close server in Slack tests
- Use a mutex for writing responses in the fake slack server
* Remove mutex at the fake slack server
Fixes a panic that would ocurr as we proxy 4xx responses. When this happens and the content type of the response is JSON we try to check if the response has a "message" key. Then, we assume that the key will contain a value of string but we don't take into account that this value can potentially be `null`.
This adds a type assertion check to to this assumption so that we can keep the original JSON body as the response if we're unable to extract an `message`.
* Fix Annotation creation
- Remove validation of panelID, now annotations are created irrespective on whether they're attached to a panel or not.
- Alwasy attach the annotation to an AlertID
* Fix annotation creation
* fix tests
* Alerting: Clear alerting rule evaluation errors after intermittent failures
When an alert transitioned in a way that `alerting -> error -> (alerting|nodata)`, the error provided by the `error` state would never be cleared thus the API and UI would show the health as an error.
* 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

* Alerting: accept mute_timing_intervals through the api for the embedded alertmanager
* add workaround for mutetimeinterval
* add mute timings to routes
* revert changes
* Update pkg/services/ngalert/api/api_alertmanager.go
* Update pkg/services/ngalert/api/api_alertmanager.go
* Update pkg/services/ngalert/api/api_alertmanager.go
* update prometheus/alertmanager dependency
* add some var docs
Refactor usage of legacy data contracts. Moves legacy data contracts
to pkg/tsdb/legacydata package.
Refactor pkg/expr to be a proper service/dependency that can be provided
to wire to remove some unneeded dependencies to SSE in ngalert and other places.
Refactor pkg/expr to not use the legacydata,RequestHandler and use
backend.QueryDataHandler instead.
* do not suppress NoData state
* extract conversion of state to postable alert + tests
* create a special alert instance if nodata
* use NoData when converting from Keep Last State instead of Alerting
* add silence during migration if NoData is mapped to KeepLastState.
