This commit changes the state package so that errors encountered while
expanding templates for custom labels and annotations are returned
from the function. This is not used at present, but will be used in the
future as we look at how to offer better feedback to users who don't
have access to logs, for example our customers who use Hosted Grafana.
This commit fixes a bug in the $values variable in notification
templates when using Classic Conditions. Since Classic Conditions
are not multi-dimensional, the values of each series that exceeded
the condition should be available as a RefID and offset. For example,
B0, B1, etc. However, this bug meant that instead just a single
condition would be printed as B, not B0.

* chore(services): replace dependencies on dashboard store with dashboard service
This continues the backend service/store split by replacing dashboard store dependencies with service dependencies. the folder service remains the single exception for now; otherwise we'd have a dependency cycle between the folder and dashboard services. I have some ideas for that, but I'll take care of all the easy parts first.
While doing this, I identified and removed a number of unused arguments from the following functions:
NewFolderNameScopeResolver
NewFolderIDScopeResolver
NewFolderUIDScopeResolver
NewDashboardIDScopeResolver
NewDashboardUIDScopeResolver
resolveDashboardScope
I have a small enterprise PR to support this commit.

This commit fixes an incorrect comment in the Result struct in eval.go
that I had written some time ago. The comment now documents the
actual behaviour and content of this field.
* Alerting: get alert rules on faults (#61248)
Two functions used to fetch alert rules from DB are updated:
- GetAlertRulesForScheduling
- ListAlertRules
Rows are scanned one by one so good ones are returned.
Common Error is logged with indication how many
rules failed on deserialization.
Resolved: #61248
* updates from review comments
This commit adds filterLabels, filterLabelsRe, removeLabels, and
removeLabelsRe functions to templates for custom labels and annotations.
It allows for use cases such as removing all private labels.
This commit changes the Data struct in template.go to use Labels
instead of map[string]string. It changes how labels are printed
when using {{ .Labels }} from map[foo:bar bar:baz] to
foo=bar, bar=baz.
This commit changes how labels are printed in templates for custom
annotations and labels from map[foo:bar bar:baz] to foo=bar, bar=baz.
Labels are comma separated, and sorted in increasing order.
This commit moves templating from the state package to a sub-package
called template. This sub-package will be the logical package for
future ease-of-use improvements to templating custom annotations
and labels.
* Use existing row struct instead of [2]string, add deserialization helper
* Replace Stream struct with stream struct which is exactly the same
* Drop unused status field
* Don't export queryRes and queryData
* Tests for custom marshalling
* Rename row fields to T and V for consistency with prometheus samples
* Rename row to sample
The `rule_groups_rules` metric is currently defined and computed by `State`.
It makes more sense for this metric to be computed off of the configured rule
set, not based on the rule evaluation state. There could be an edge condition
where a rule does not have a state yet, and so is uncounted.
Additionally, we would like this metric (and others), to have a `rule_group`
label, and this is much easier to achieve if the metric is produced from the
`Scheduler` package.

valuable for troubleshooting Alertmanager operation particularly in HA setups.

Note that `alertmanager_dispatcher_aggregation_group_limit_reached_total` is
explicitly not exposed, as the group limit metrics are not enabled.

This adds provisioning endpoints for downloading alert rules and alert rule groups in a
format that is compatible with file provisioning. Each endpoint supports both json and
yaml response types via Accept header as well as a query parameter
download=true/false that will set Content-Disposition to recommend initiating a download
or inline display.
This also makes some package changes to keep structs with potential to drift closer
together. Eventually, other alerting file structs should also move into this new file
package, but the rest require some refactoring that is out of scope for this PR.

* Alerting: Fix Test Receivers when settings are non-strings
As part of the Alerting extraction, we want to make sure we don't have circular depedencies. As such, I had to move `PostableGrafanaReceiver` to a new struct in `grafana/alerting` called `GrafanaReceiver`.
`PostableGrafanaReceiver` has an attribute called `Settings` that uses a Grafana-propietary struct called `RawMessage`, this struct shadows `json.RawMessage`.
When I created `GrafanaReceiver`, I turned settings into a `map[string]string` thinking all settings would end up as strings. This was a mistake, and this test proves that it doesn't work, and breaks the API.
