This creates a new `model` directory and moves all data-model related
packages over there:
exemplar labels relabel rulefmt textparse timestamp value
All the others are more or less utilities and have been moved to `util`:

The rules manager keeps a note of which series were generated by the
last run, so it can write a stale marker to those that disappeared.
Since the keys are not for human eyes, we can use a simpler format
and save the effort of quoting label values.

I think we should increment the metric here, we're setting the rule
health anyways. This means even if the "evaluation" suceeded, none of
the samples made it to storage.
This is a simplified solution to: https://github.com/prometheus/prometheus/pull/8410/

This moves the label lookup into TSDB, whilst still keeping the cached-ref optimisation for repeated Appends.
This makes the API easier to consume and implement. In particular this change is motivated by the scrape-time-aggregation work, which I don't think is possible to implement without it as it needs access to label values.

To load ALERT_FOR_STATE only `storage.Queryable` interface is required,
so this patch uses this narrower interface for to perform this.

Rather than sending a value to the done channel on a group to indicate
whether or not to add stale markers to a closing rule group use an
explicit boolean. This allows more functions than just run() to read
from the done channel and fixes an issue where Eval() could consume the
channel during an update, causing run() to never return.
