Fix is to add json tags to `Metadata` struct. Absence of these tags
causes Go to use the field name, which starts with an upper-case
letter and breaks the protocol.
Extend tests to verify the JSON response.

Aggregations discard the metric name, so don't try to
include it in the error message.
Add a test that generates this warning.

On the incoming path, `writeHandler.write()` creates a new table for
each request.
`labelProtosToLabels` takes a `ScratchBuilder` now.
Call `NewScratchBuilder` as required in tests.

The individual strings for label names and values are held in a table,
and each Labels value is a run of varint-encoded indexes into that table.
When creating new labels, a sync.Mutex is locked around reads and writes.
When reading labels, there is no locking because the table of strings
used by those labels is immutable.

Since we want to use a faster gzip/zlib libraries we should add a lint check so that it's used everywhere

Clarify in the first comment that it is `watch()` that waits, and reduce
verbiage.
The second comment was slightly contradictory to the first and otherwise
didn't seem to add much, since `currentSegment` was incremented just a
few lines later.

* fix bug that would cause us to only read from the WAL on the 15s
fallback timer if remote write had fallen behind and is no longer
reading from the WAL segment that is currently being written to

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/.

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.
