* Alerting: Use Alertmanager types extracted into grafana/alerting
We're in the process of exporting all Alertmanager types into grafana/alerting so that they can be imported in the Mimir Alertmanager, without a neeed to import Grafana directly.
This change introduces type aliasing for all Alertmanager types based on their 1:1 copy that now live in grafana/alerting.

Updates Grafana Alertmanager to work with new interface from grafana/alerting#161. This change stops passing user-defined templates to the Grafana Alertmanager by persisting them to disk and instead passes them by string.
* ValidateInterval doesn't need the entire config
* Validation no longer depends on entire folder now that we've dropped foldertitle from api
* Don't depend on entire config struct
* Export validate group
* Alerting: feat: support deleting rule groups in the provisioning API
Adds support for DELETE to the provisioning API's alert rule groups route, which allows deleting the rule group with a
single API call. Previously, groups were deleted by deleting rules one-by-one.
Fixes#81860
This change doesn't add any new paths to the API, only new methods.

This commit adds basic support for time_intervals, as mute_time_intervals
is deprecated in Alertmanager and scheduled to be removed before 1.0.
It does not add support for time_intervals in API or file provisioning,
nor does it support exporting time intervals. This will be added in
later commits to keep the changes as simple as possible.
Previously receivers were only validated before saving the alertmanager
configuration. This is a suboptimal experience for those upgrading with preview
as the failed channel upgrade will return an API error instead of being
summarized in the table.
Adds a feature flag (alertingUpgradeDryrunOnStart) that will dry-run the legacy
alert upgrade on startup. It is enabled by default.
When on legacy alerting, this feature flag will log the results of the legacy
alerting upgrade on startup and draw attention to anything in the current legacy
alerting configuration that will cause issues when the upgrade is eventually
performed. It acts as a log warning for those where action is required before
upgrading to Grafana v11 where legacy alerting will be removed.
If the db already has an entry in the kvstore for the silences of an
alertmanager before the migration has taken place, then it's possible that the
active alertmanager will overwrite the silence file created by the migration
before it has a chance to load it into memory.
This should not happen normally but is possible in edge-cases.
This change opts to bypass the unnecessary step of writing the silences to disk
during the migration and instead write them directly to the kvstore. This avoids
the race condition entirely and is more correct as we treat the database as the
source of truth for AM state.
Alerting: Remove start page of upgrade preview
Alerting upgrade page will now always show the summary table even before
upgrading any alerts or notification channels. There a few reasons for this:
- The information on the start page is redundant as it's now contained in the
documentation.
- Previously, if some unexpected issue prevented performing a full upgrade, a
user would have limited to no means to using the preview tool to help fix the
problem. This is because you could not see the summary table until the full
upgrade was performed at least once. Now, you can upgrade individual alerts and
notification channels from the beginning.

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

* 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
