Description:

Adds a new configuration option: trim_metric_suffixes to the prometheus receiver. When set to true, suffixes will be trimmed from metrics. This replaces use of thepkg.translator.prometheus.NormalizeName feature-gate in the prometheus receiver, but leaves it for exporters.

The first commit simplifies the usage of the feature-gate. The tests and implementation were passing around an entire registry when it wasn't necessary.

Link to tracking Issue:

Part of #21743
Part of #8950

Testing:

Unit tests.

Documentation:

Added to the README.

Why do we need pkg.translator.prometheus.NormalizeName feature gate if it is controlled by config options now? Maybe we should just deprecate it as the first step? Keeping add_type_and_unit_suffixes disabled for some time on the exporter side would be the same as keeping pkg.translator.prometheus.NormalizeName in alpha the state, but maybe it's even unnecessary... It just seems a bit confusing having several controls for the same behavior.

The feature gate is useful if we still consider the feature alpha. Do you think we need to resolve #23208 before graduating it to beta?

If everyone agrees it is beta, we can remove it as part of adding the config options.

#23208 is only about the receiver. Given that the option trim_metric_suffixes is off by default, it won't affect users unless they explicitly enable it. I think we can just mark the config option as experimental and subject to change until #23208 is resolved

That works for me. I'll update this to remove the feature gate from the receiver path.

@dmitryax done. I marked the config option experimental in the README.

prometheusreceiver: remove unused buffer_period and buffer_count conf…

…iguration options (#24257)

**Description:**

Fixes #24258

Found while adding documentation for
#24256.
The prometheus receiver had two config options that AFAICT have never
been used.

The config options have existed since the very first commit ever for the
Prometheus receiver:
