Revert accidental breakage of custom labels that was a unfortunate
leftover from some development/testing.

Implement OpenTelemetry metric instruments covering the same set
of RDT features as the existing Prometheus metrics collector.

Notes: Unfortunately we can't get fully identical metrics using
otel. Due to how otel translates otel instruments to prometheus
metrics, we either end up with different types (gauge vs. counter)
or extra metric name suffices derived from types and units.
