Describe the issue you're reporting

Throughout the years, we've seen several different projects develop their own codebases to translate OTLP metrics and attribute names into Prometheus naming conventions, including collector contrib, which developed the package pkg/translator/prometheus.

The problem is that this codebase is not usable for other projects like Prometheus and OTel-Go SDK, since it creates cyclic dependencies and uses Global registries for feature gates.

A group inside the Prometheus team has developed https://github.com/prometheus/otlptranslator to centralize the development of those translations. We're currently working on migrating all codebases to that library and we'd love to do the same here

We should reach out to importers of this library as well, as shown at https://pkg.go.dev/github.com/open-telemetry/opentelemetry-collector-contrib/pkg/translator/prometheus@v0.125.0?tab=importedby
