* Alerting: Repurpose rule testing endpoint to return potential alerts
This feature replaces the existing no-longer in-use grafana ruler testing API endpoint /api/v1/rule/test/grafana. The new endpoint returns a list of potential alerts created by the given alert rule, including built-in + interpolated labels and annotations.
The key priority of this endpoint is that it is intended to be as true as possible to what would be generated by the ruler except that the resulting alerts are not filtered to only Resolved / Firing and ready to be sent.
This means that the endpoint will, among other things:
- Attach static annotations and labels from the rule configuration to the alert instances.
- Attach dynamic annotations from the datasource to the alert instances.
- Attach built-in labels and annotations created by the Grafana Ruler (such as alertname and grafana_folder) to the alert instances.
- Interpolate templated annotations / labels and accept allowed template functions.
* Alerting: Tiny refactor on the eval and schedule packages
two very small things:
- We had a constructor on something called a `Context` which is not a `context.Context` so let's just name that constructor `NewContext`
- The user that we use to run query evaluations is the same (with some variation) abstract it to a function so that it can be re-used when necessary.

* stop using the scheduler's Update and Delete methods all communication must be via the database
* update scheduler's registry to calculate diff before re-setting the cache
* update fetcher to return the diff generated by registry
* update processTick to update rule eval routine if the rule was updated and it is not going to be evaluated at this tick.
* remove references to the scheduler from api package
* remove unused methods in the scheduler
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.

* add: IsServiceAccount to SignedInUser and IsRealUser

a uniqueID, see comment: https://github.com/grafana/grafana/pull/58015#discussion_r1011361880
