discovery/kubernetes: Support node role selectors for pod roles
...
The node informers for pod roles respected filtering based on selectors
([1]). However, node selectors for pod roles were not allowed. This
patch address that, and additionally adds pod filtering logic, to not
populate their target groups when they belong to a filtered node.

fix(config): check all fields in GlobalConfig.isZero()
...
The isZero() method was missing checks for 9 fields that exist in the
GlobalConfig struct. This caused the method to incorrectly return true
when only these fields had non-zero values, resulting in user
configurations being silently overwritten with defaults during YAML
unmarshaling.
Added checks for: BodySizeLimit, SampleLimit, TargetLimit, LabelLimit,
LabelNameLengthLimit, LabelValueLengthLimit, KeepDroppedTargets,
MetricNameValidationScheme, and MetricNameEscapingScheme.
Consolidated TestEmptyGlobalBlock and new isZero tests under
TestGlobalConfig.

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

Phase out native histogram feature flag
...
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.

Apply analyzer "modernize" to the whole codebase
...
See
https://pkg.go.dev/golang.org/x/tools/gopls/internal/analysis/modernize
for details.
This ran into a few issues (arguably bugs in the modernize tool),
which I will fix in the next commit, so that we have transparency what
was done automatically.
Beyond those hiccups, I believe all the changes applied are
legitimate. Even where there might be no tangible direct gain, I would
argue it's still better to use the "modern" way to avoid micro
discussions in tiny style PRs later.

Revert: OTLP Support including scope metadata as metric labels ( #16842 )

Reverts #16730 and #16760
This is being done because we've noticed a problem in the spec that could
lead to name collisions if attributes name, version or schema_url are added
to the scope. They would collide with the already reserved labels
otel_scope_name, otel_scope_version and otel_scope_schema_url.
Since this new configuration option never made it into a release, we can
safely remove it from the 3.5 release. We'll sort this out for the 3.6 release

fix(config): respect GOGC environment variable if no "runtime" block exists
...
Fixes: https://github.com/prometheus/prometheus/issues/16334
Related to:
- https://github.com/prometheus/prometheus/pull/15238
- https://github.com/prometheus/prometheus/pull/16052
Currently, when the GOGC environment variable is set -- and no `runtime`
block is set in the Prometheus config file -- it is ignored and the
default value of 75% is always used.
However, if there is an empty runtime block (e.g. `runtime: {}`), _then_
the GOGC environment variable is checked.
This PR changes this behavior to consistently check and use the GOGC
environment variable when it is set (unless the `gogc` field is set in
the `runtime` block of the loaded config file, in which case it still
gives that precedence).

scrape: Add config option for escaping scheme request. ( #16066 )
...
The new metric_name_escaping_scheme config option works in parallel with metric_name_validation_scheme and controls which escaping scheme is requested when scraping. When not specified, the scheme will request underscores if the validation scheme is set to legacy, and will request allow-utf-8 when the validation scheme is set to utf8. This setting allows users to allow utf8 names if they like, but explicitly request an escaping scheme rather than UTF-8.

scraper: fix UTF-8 scraping header always sent with PrometheusText1.0.0
...
The `Accept` header should not include `escape=allow-utf-8` unless
explicitly requested.
Conveniently, there was already a test covering this header's value, it
just required updating so it also asserts that this value in the header
is not set in the cases we don't expect it to be set. I also converted
those tests into table tests to help make failures clearer.
