`histogram.Error` becomes the generic wrapper type for all histogram errors.
This makes it easier and less error prone when adding new errors to check if
an error is an histogram error as well as making it less error prone to convert
the errors.
This change the type of those specific sentinel errors from error to
`histogram.Error`, but it should almost never matter.
e.g., `errors.Is(err, ErrHistogram...)` would still work out of the box.

Add logic to the target_info metric generation in the OTLP endpoint, so that any samples with the same timestamp for the same (target_info) series are de-duplicated. It comes out of a user's bug report about duplicated target_info samples in Grafana Mimir (which uses the Prometheus target_info generation logic).
If I'm not mistaken, duplicate target_info samples should stem from multiple resources in the same OTLP request being translated to the same target_info label set. It shouldn't be caused by a Prometheus bug.
* Correctly generate rulesLintConfig when --lint=none is set (#17399)
If I run promtool check config --lint=none I get:
```
Checking rules.yml
FAILED:
rules.yml: unset nameValidationScheme
```
This is because passing --lint=none stops newConfigLintConfig from generating rulesLintConfig which is needed for validation.
It means that defaults are used then, one of which is unset value for metric name validation, causing this error.
Fix this by handling --lint=none case correctly and still generating rulesLintConfig.

* Add WriteProto method and tests for promtool metrics
This commit adds:
1. WriteProto method to storage/remote/client.go that handles
marshaling and compression of protobuf messages
2. Updated parseAndPushMetrics in cmd/promtool/metrics.go to use
the new WriteProto method
3. Comprehensive tests for PushMetrics functionality
The WriteProto method provides a cleaner API for sending protobuf
messages without manually handling marshaling and compression.

Mark as stable means that breaking changes are only allowed together with
major version release of Prometheus.

TestScrapeLoop_HistogramBucketLimit tests the bucket limiter but it also sets sample_limit to the same value, which seems incorrect.
Signed-off-by: Lukasz Mierzwa <l.mierzwa@gmail.com>
Currently histograms bypass sample_limit logic as the limitAppender only implements the Append() method, while histograms are appended using AppendHistogram.
This means that they are effectively ignored during sample_limit checks and a scrape with sample_limit=100 and 500 histograms will accept all samples.
Add AppendHistogram method to the limitAppender so histograms are also counted towards sample_limit.

This reverts commit 93887a9b82a71613067ff0706248c18fe131c5b0.
See discussion at https://github.com/prometheus/prometheus/pull/17240 - I had
thought this was a simple and clear bugfix, but multiple people were depending
on the previous behavior already, and we want to err on the side of stability.
