fix: PrometheusNotIngestingSamples label matching
This alert will never return anything as the left side of the query has
the labels `[component, environment, instance, job, type]` while the
right side has `[component, environment, instance, job]`.

The `type` label was added to `prometheus_tsdb_head_samples_appended_total` in this PR but the mixin wasn't updated
for the new label: https://github.com/prometheus/prometheus/pull/11395

This was found with [pint](https://github.com/cloudflare/pint) PromQL

Bryan Boreham 14b4fbc2ff labels: make InternStrings a no-op for stringlabels version
The current implementation of `InternStrings` will only save memory
when the whole set of labels is identical to one already seen, and this
cannot happen in the one place it is called from in Prometheus,
remote-write, which already detects identical series.

Marco Pracucci 501bc6419e
Add ShardedPostings() support to TSDB (#10421)
This PR is a reference implementation of the proposal described in #10420.

In addition to what described in #10420, in this PR I've introduced labels.StableHash(). The idea is to offer an hashing function which doesn't change over time, and that's used by query sharding in order to get a stable behaviour over time. The implementation of labels.StableHash() is the hashing function used by Prometheus before stringlabels, and what's used by Grafana Mimir for query sharding (because built before stringlabels was a thing).

Follow up work
As mentioned in #10420, if this PR is accepted I'm also open to upload another foundamental piece used by Grafana Mimir query sharding to accelerate the query execution: an optional, configurable and fast in-memory cache for the series hashes.
