* extract to getRuleExtraLabels
* move populating of constant rule labels to extra labels
* AlertRule to return condition
* update ConditionEval to not return an error because it's always nil
* make getExprRequest private
* refactor executeCondition to just converter and move execution to the ConditionEval as this makes code more readable.
* log error if results have errors
* change signature of evaluate function to not return an error
* Introduce AlertsRouter in the sender package, and move all fields and methods related to notifications out of the scheduler to this router.
* Introduce a new interface AlertsSender in the schedule package and replace calls of anonymous function `notify` inside the ruleRoutine to calling methods of that interface.
* Rename interface Scheduler in api package to ExternalAlertmanagerProvider, and replace scheduler with AlertRouter as struct that implements the interface.
* 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: Add first Grafana reserved label g_label
g_label holds the title of the folder container the alert. The intention of this label
is to use it as part of the new default notification policy groupBy.
* Add nil check on updateRule labels map
* Disable gocyclo lint on schedule.ruleRoutine
will remove later in a separate refactoring PR to reduce complexity.

* Alerting: decapitalize log lines and use "err" as the key for errors
Found using (logger|log).(Warn|Debug|Info|Error)\([A-Z] and (logger|log).(Warn|Debug|Info|Error)\(.+"error"
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.

* remove not used code:
- remove offset in ticket because it is not used
- remove unused ticker and scheduler methods
* use duration for interval
* add metrics grafana_alerting_ticker_last_consumed_tick_timestamp_seconds, grafana_alerting_ticker_next_tick_timestamp_seconds, grafana_alerting_ticker_interval_seconds
* make eval.Evaluator an interface
* inject Evaluator to TestingApiSrv
* move conditionEval to RouteTestGrafanaRuleConfig because it is the only place where it is used
* update rule test api to check data source permissions
* Fix evaluation of alert rules for datasources with custom headers
* Fix unit tests
* Fix integration tests
* Evaluator fields should be package private
* (WIP) send alerts to external, internal, or both alertmanagers
* Modify admin configuration endpoint, update swagger docs
* Integration test for admin config updated
* Code review changes
* Fix alertmanagers choice not changing bug, add unit test
* Add AlertmanagersChoice as enum in swagger, code review changes
* Fix API and tests errors
* Change enum from int to string, use 'SendAlertsTo' instead of 'AlertmanagerChoice' where necessary
* Fix tests to reflect last changes
* Keep senders running when alerts are handled just internally
* Check if any external AM has been discovered before sending alerts, update tests
* remove duplicate data from logs
* update comment
* represent alertmanagers choice as an int instead of a string
* default alertmanagers choice to all alertmanagers, test cases
* update definitions and generate spec
* 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.
* 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 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.
* move evaluation function out of loop
* extract updateRule function
* isolate alertRule change. update returns new rule and the evaluation accepts the rule as argument
* extract retry loop into a function
* add function wide log context.
* refactor metrics + add tests + replace timeNow with schedule.clock
