* 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.

* Alerting: Validate contact point configuration during migration to Unified Alerting (#40717)
* Alerting: Validate contact point configuration during the migration
This minimises the chances of generating broken configuration as part of the migration. Originally, we wanted to generate it and not produce a hard stop in Grafana but this strategy has the chance to avoid delivering notifications for our users.
We now think it's better to hard stop the migration and let the user take care of resolving the configuration manually.

* Alerting: Fixes a bug when trying to sync broken alertmanager config (#40338)
* Alerting: Fixes a bug when trying to sync broken alertmanager config
Broken alertmanager configuration has the potential to be introduced as part of a migration e.g. due to incompatible data between what grafana accepts and what the Alertmanager expects. When this happens, we expect an eventually consistent behaviour where we'll keep trying to apply the configuration until it works.
As part of change in https://github.com/grafana/grafana/pull/39237 we introduced a regression that modified this behaviour and instead tried to create a new Alertmanager for that organization everytime, which eventually ended up in a panic due to a duplicate metrics being registered.
This PR fixes that and introduces a test to catch further regressions.

Remove validation for labels to be accepted in the Alertmanager, This helps with datasources that produce non-compatible labels.
Adds an "object_matchers" to alert manager routers so we can support labels names with extended characters beyond prometheus/openmetrics. It only does this for the internal Grafana managed Alert Manager.
This requires a change to alert manager, so for now we use grafana/alertmanager which is a slight fork, with the intention of going back to upstream.
The frontend handles the migration of "matchers" -> "object_matchers" when the route is edited and saved. Once this is done, downgrades will not work old versions will not recognize the "object_matchers".

* pass url parameters through context.Context
* fix url param names without colon prefix
* change context params to vars
* replace url vars in tests using new api
* rename vars to params

* rename seturlvars to seturlparams
* Chore: GetDashboardQuery should be dispatched using DispatchCtx
* Fix after merge
* Changes after review
* Various fixes
* Use GetDashboardCtx function instead of GetDashboard
* Alerting: Refactor & fix unified alerting metrics structure
Fixes and refactors the metrics structure we have for the ngalert service. Now, each component has its own metric struct that includes the JUST the metrics it uses. Additionally, I have fixed the configuration metrics and added new metrics to determine if we have discovered and started all the necessary configurations of an instance.
This allows us to alert on `grafana_alerting_discovered_configurations - grafana_alerting_active_configurations != 0` to know whether an alertmanager instance did not start successfully.
* Alerting: Persist notification log and silences to the database
This removes the dependency of having persistent disk to run grafana alerting. Instead of regularly flushing the notification log and silences to disk we now flush the binary content of those files to the database encoded as a base64 string.
* Change templateCaptureValue to support using template functions
This commit changes templateCaptureValue to use float64 for the value
instead of *float64. This change means that annotations and labels can
use the float64 value with functions such as printf and avoid having to
check for nil. It also means that absent values are now printed as 0.
* Use math.NaN() instead of 0 for absent value
* Alerting: Fix alert flapping in the alertmanager
fixes a bug that caused Alerts that are evaluated at low intervals (sub 1 minute), to flap in the Alertmanager.
Mostly due to a combination of `EndsAt` and resend delay.
The Alertmanager uses `EndsAt` as a heuristic to know whenever it should resolve a firing alert, in the case that it hasn't heard
back from the alert generation system.
Because grafana sent the alert with an `EndsAt` which is equal to the `For` of the alert itself,
and we had a hard-coded 1 minute re-send delay (only applicable to firing alerts) this meant that a firing alert would resolve in the Alertmanager before we re-notify that it still firing.
This commit, increases the `EndsAt` by 3x the the resend delay or alert interval (depending on which one is higher). The resendDelay has been decreased to 30 seconds.
Introduces org-level isolation for the Alertmanager and its components.
Silences, Alerts and Contact points are not separated by org and are not shared between them.

This commit adds contact point testing to ngalerts via a new API
endpoint. This endpoint accepts JSON containing a list of
receiver configurations which are validated and then tested
with a notification for a test alert. The endpoint returns JSON
for each receiver with a status and error message. It accepts
a configurable timeout via the Request-Timeout header (in seconds)
up to a maximum of 30 seconds.
* Alerting: Expose discovered and dropped Alertmanagers
Exposes the API for discovered and dropped Alertmanagers.
* make admin config poll interval configurable
* update after rebase
* wordsmith
* More wordsmithing
* change name of the config
* settings package too
