Partially fixes https://github.com/prometheus/prometheus/issues/17416 by
renaming all CT* names to ST* in the whole codebase except RW2 (this is
done in separate
[PR](https://github.com/prometheus/prometheus/pull/17411)) and
PrometheusProto exposition proto.
```
CreatedTimestamp -> StartTimestamp
CreatedTimeStamp -> StartTimestamp
created_timestamp -> start_timestamp
CT -> ST
ct -> st

As a follow-up to #17344, add two configuration parameters for controlling label
name translation, both defaulting to on for backwards compatibility (currently
these behaviours are hardcoded as enabled):
* otlp.label_name_underscore_sanitization => Prefix label names starting with a
single underscore with key_ when translating OTel attribute names
* otlp.label_name_preserve_multiple_underscores => Keep multiple consecutive
underscores in label names when translating OTel attribute names

This adds:
* A `ScrapePoolConfig()` method to the scrape manager that allows getting
the scrape config for a given pool.
* An API endpoint at `/api/v1/targets/relabel_steps` that takes a pool name
and a label set of a target and returns a detailed list of applied
relabeling rules and their output for each step.
* A "show relabeling" link/button for each target on the discovery page
that shows the detailed flow of all relabeling rules (based on the API
response) for that target.
Note that this changes the JSON encoding of the relabeling rule config
struct to output the original snake_case (instead of camelCase) field names,
and before merging, we need to be sure that's ok :) See my comment about
that at https://github.com/prometheus/prometheus/pull/15383#issuecomment-3405591487

The detailed plan for this is laid out in
https://github.com/prometheus/prometheus/issues/16572 .
This commit adds a global and local scrape config option
`scrape_native_histograms`, which has to be set to true to ingest
native histograms.
To ease the transition, the feature flag is changed to simply set the
default of `scrape_native_histograms` to true.
Further implications:
- The default scrape protocols now depend on the
`scrape_native_histograms` setting.
- Everywhere else, histograms are now "on by default".
Documentation beyond the one for the feature flag and the scrape
config are deliberately left out. See
https://github.com/prometheus/prometheus/pull/17232 for that.

Adds a `config` label (similar to `prometheus_sd_discovered_targets`) to
refresh metrics to help identify the source of refresh issues or
performance stats. In particular for HTTP SD, it can be common to have
multiple disparate HTTP SD sources that should be identified and not
lumped together. For example if one HTTP SD service has failures, that
should be evident in its own time series seperate from other HTTP SD
sources.
`config` seemed more appropriate than `endpoint` as a general standard
for `prometheus_sd` metrics.
Docs were also updated for HTTP SD to point at the new refresh metrics
rather than the older metrics.

* Add anchored and smoothed to vector selectors.
This adds "anchored" and "smoothed" keywords that can be used following a matrix selector.
"Anchored" selects the last point before the range (or the first one after the range) and adds it at the boundary of the matrix selector.
"Smoothed" applies linear interpolation at the edges using the points around the edges. In the absence of a point before or after the edge, the first or the last point is added to the edge, without interpolation.
*Exemple usage*
* `increase(caddy_http_requests_total[5m] anchored)` (equivalent of *caddy_http_requests_total - caddy_http_requests_total offset 5m* but takes counter reset into consideration)
* `rate(caddy_http_requests_total[step()] smoothed)`

Because the label API endpoints read from the TSDB indexes, they can
return information for series which are present in the index but have no
samples in the queried interval.
Add similar note for the series endpoint.

This mostly handles the cases mentioned in #16576. However, there are
some related changes in here, too:
- Some line formatting to avoid lines longer than 80 characters.
- Establish in basics.md that histograms have a counter vs. gauge
"flavor" that is also stored in the sample and not just by
convention as for float samples.
- Add the documentation of the unary minus, which was missing so far.
This require a bit of restructuring.
- Cleaned up a few references to "Prometheus" that should better refer
to "PromQL" (and "Prometheus's query language" → "PromQL" etc.).
I decided to not explain in all detail when and how PromQL detects an
incompatible counter reset. The spec is linked from basics.md, so the
minority that might be interested in this can still look it up.
