* NHCB: scrape use state field and not booleans
From comment https://github.com/prometheus/prometheus/pull/14978#discussion_r1800898724
Also make compareLabels read only and move storeLabels to the first
processed classic histogram series.

scrape: Remove implicit fallback to the Prometheus text format
Remove implicit fallback to the Prometheus text format in case of invalid/missing Content-Type and fail the scrape instead. Add ability to specify a `fallback_scrape_protocol` in the scrape config.

For: #14355
This commit updates Prometheus to adopt stdlib's log/slog package in
favor of go-kit/log. As part of converting to use slog, several other
related changes are required to get prometheus working, including:
- removed unused logging util func `RateLimit()`
- forward ported the util/logging/Deduper logging by implementing a small custom slog.Handler that does the deduping before chaining log calls to the underlying real slog.Logger
- move some of the json file logging functionality to use prom/common package functionality
- refactored some of the new json file logging for scraping
- changes to promql.QueryLogger interface to swap out logging methods for relevant slog sugar wrappers
- updated lots of tests that used/replicated custom logging functionality, attempting to keep the logical goal of the tests consistent after the transition
- added a healthy amount of `if logger == nil { $makeLogger }` type conditional checks amongst various functions where none were provided -- old code that used the go-kit/log.Logger interface had several places where there were nil references when trying to use functions like `With()` to add keyvals on the new *slog.Logger type

* scrape/scrape_test.go: reduce the time it takes to reload the manager
TestNativeHistogramMaxSchemaSet took over 3x5s to complete because
there's a minimum reload interval.
I've made the testcases run in parallel and reduced the reload interval
to 10ms. Now the test runs in around 0.1-0.2 seconds.
Ran test 10000 times to check if it's flaky.

Resolved by dropping the UTF-8 feature flag and adding the
`auto-reload-config` feature flag.
For the new web ui pick all changes from `main`.
This change causes Prometheus to allow all UTF-8 characters in metric and label names.
This means that names that were previously invalid and would have been previously rejected will be allowed through.

The following configuration snippet calls
http://127.0.0.1:8000/?foo=value1 instead of
http://127.0.0.1:8000/?foo=value2.
This is incorrect, the labels of the target should be prefered.
```yaml
- job_name: local
params:
foo: [value1]
static_configs:
- targets: ['127.0.0.1:8000']
labels:
__param_foo: value2
```

So long as they specify timestamps. We don't check that the timestamps
are different.
Extend test, and use client_golang/prometheus/testutil to simplify metric check.

Up until this point, if a scrape was done with the protobuf format Prometheus would always try to ingest native histograms even with the feature flag disabled. This causes problems with other feature-flags that depend on the protobuf format, like 'created-timestamp-zero-ingestion'. This commit decouples native histogram parsing from ingestion, making sure ingestion only happens when the 'native-histogram' feature-flag is enabled.

This call bloats checkAddError signature and logic, we can and should call it from the main scrape logic.
