This pull request updates our fork of Alertmanager to commit 65bdab0, which is based on commit 5658f8c in Prometheus Alertmanager.
It applies the changes from grafana/alerting#155 which removes the overrides for validation of alerts, labels and silences that we had put in place to allow alerts and silences to work for non-Prometheus datasources. However, as this is now supported in Alertmanager with the UTF-8 work, we can use the new upstream functions and remove these overrides.
The compat package is a package in Alertmanager that takes care of backwards compatibility when parsing matchers, validating alerts, labels and silences. It has three modes: classic mode, UTF-8 strict mode, fallback mode. These modes are controlled via compat.InitFromFlags. Grafana initializes the compat package without any feature flags, which is the equivalent of fallback mode. Classic and UTF-8 strict mode are used in Mimir.
While Grafana Managed Alerts have no need for fallback mode, Grafana can still be used as an interface to manage the configurations of Mimir Alertmanagers and view configurations of Prometheus Alertmanager, and those installations might not have migrated or being running on older versions. Such installations behave as if in classic mode, and Grafana must be able to parse their configurations to interact with them for some period of time. As such, Grafana uses fallback mode until we are ready to drop support for outdated installations of Mimir and the Prometheus Alertmanager.

This commit prevents saving configurations containing inhibition
rules in Grafana Alertmanager. It does not reject inhibition
rules when using external Alertmanagers, such as Mimir. This meant
the validation had to be put in the MultiOrgAlertmanager instead of
in the validation of PostableUserConfig. We can remove this when
inhibition rules are supported in Grafana Managed Alerts.
AM config applied via API would use the PostableUserConfig as the AM raw
config and also the hash used to decide when the AM config has changed.
However, when applied via the periodic sync the PostableApiAlertingConfig would
be used instead.
This leads to two issues:
- Inconsistent hash comparisons when modifying the AM causing redundant applies.
- GetStatus assumed the raw config was PostableUserConfig causing the endpoint
to return correctly after a new config is applied via API and then nothing once
the periodic sync runs.
Note: Technically, the upstream GrafanaAlertamanger GetStatus shouldn't be
returning PostableUserConfig or PostableApiAlertingConfig, but instead
GettableStatus. However, this issue required changes elsewhere and is out of
scope.

* Alerting: During legacy migration reduce the number of created silences
During legacy migration every migrated rule was given a label rule_uid=<uid>.
This was used to silence DatasourceError/DatasourceNoData alerts for
migrated rules that had either ExecutionErrorState/NoDataState set to
keep_state, respectively.
This could potentially create a large amount of silences and a high cardinality
label. Both of these scenarios have poor outcomes for CPU load and latency in
unified alerting.
Instead, this change creates one label per ExecutionErrorState/NoDataState when
they are set to keep_state as well as two silence rules, if rules with said
labels were created during migration. These silence rules are:
- __legacy_silence_error_keep_state__ = true
- __legacy_silence_nodata_keep_state__ = true
This will drastically reduce the number of created silence rules in most cases
as well as not create the potentially high cardinality label `rule_uid`.
These don't get marshalled and unmarshalled in the same way as they are represented in Go
This PR changes the OpenAPI spec to reflect what the API accepts and sends back
* Simple, per-base-interval jitter
* Add log just for test purposes
* Add strategy approach, allow choosing between group or rule
* Add flag to jitter rules
* Add second toggle for jittering within a group
* Wire up toggles to strategy
* Slightly improve comment ordering
* Add tests for offset generation
* Rename JitterStrategyFrom
* Improve debug log message
* Use grafana SDK labels rather than prometheus labels
* ngalert openapi: Use same `basePath` as rest of Grafana
Currently, there are two issues that prevent easily merging `ngalert` and grafana openapi specs:
- The basePath is different. `grafana` has `/api` and `ngalert` has `/api/v1`. I changed `ngalert` to use `/api`
- The `ngalert` endpoints have their basePath in the each operation path. The basePath should actually be omitted
