* Expand the value of math and reduce expressions in annotations and labels
This commit makes it possible to use the values of reduce and math
expressions in annotations and labels via their RefIDs. It uses the
Stringer interface to ensure that "{{ $values.A }}" still prints the
value in decimal format while also making the labels for each RefID
available with "{{ $values.A.Labels }}" and the float64 value with
"{{ $values.A.Value }}"
* Alerting: Refactor state manager as a dependency
Within the scheduler, the state manager was being passed around a
certain number of functions. I've introduced it as a dependency to keep
the "service" interfaces as clean and homogeneous as possible.
This is relevant, because I'm going to introduce live reload of these
components as part of my next PR and it is better if dependencies are
self-contained.
* remove unused functions
* Fix a few more tests
* Make sure the `stateManager` is declared before the schedule
* Alerting: Expand `{{$labels.xyz}}` template in labels and annotations

* Fix annotation not updating for same alert

When, and currently only when using a classic condition, evaluation information is added (which is like the EvalMatches from dashboard alerting).
This is returned via the API and can be included in notifications by reading the `__value__` label attached `.Alerts` in the template. It is a string.
Instead put in package folder but with package name suffixed with _test
This enables code coverage within the pkg while still allow the tests to operate from external to package perspective (only exported things).
