- Rename -opentelemetry.sanitizeMetrics command-line flag to more clear -opentelemetry.usePrometheusNaming
- Clarify the description of the change at docs/CHANGELOG.md
- Rename promrelabel.SanitizeLabelNameParts to more clear promrelabel.SplitMetricNameToTokens
- Properly split metric names at '_' char in promerlabel.SplitMetricNameToTokens.
- Add tests for various edge cases for Prometheus metric names' normalization
according to the code at b865505850/pkg/translator/prometheus/normalize_name.go
- Extract the code responsible for Prometheus metric names' normalization into a separate file (santize.go)
