Owen Williams a28d7865ad UTF-8: Add support for parsing UTF8 metric and label names 
This adds support for the new grammar of `{"metric_name", "l1"="val"}` to promql and some of the exposition formats.
This grammar will also be valid for non-UTF-8 names.
UTF-8 names will not be considered valid unless model.NameValidationScheme is changed.

This does not update the go expfmt parser in text_parse.go, which will be addressed by https://github.com/prometheus/common/issues/554/.

Part of https://github.com/prometheus/prometheus/issues/13095

Bryan Boreham c0e36e6bb3 Standardise exemplar label as "trace_id" 
This is consistent with the OpenTelemetry standard, and an example in OpenMetrics.

Matthias Loibl 0b38a5b774
Update go get buf.build in README.md 
The old import path stopped working. 

```
go get go.buf.build/protocolbuffers/go/prometheus/prometheus
go: unrecognized import path "go.buf.build/protocolbuffers/go/prometheus/prometheus": https fetch: Get "https://go.buf.build/protocolbuffers/go/prometheus/prometheus?go-get=1": dial tcp: lookup go.buf.build on 192.168.2.1:53: no such host
```

We should instead tell users to use the new import paths.

beorn7 86d7618d84 promql: Fix wrongly scoped range vectors 
Fixes #11708.

If a range vector is fixen in time with the @ modifier, it gets still
moved around for different steps in a range query. Since no additional
points are retrieved from the TSDB, this leads to steadily emptying
the range, leading to the weird behavior described in isse #11708.

This only happens for functions listed in `AtModifierUnsafeFunctions`,
and the only of those that takes a range vector is `predict_linear`,
which is the reason why we see it only for this particular function.
