This change is for demo purposes, exploring the benefits (and downsides)
for the complex type format for OM2 captured in
https://github.com/prometheus/docs/pull/2679.
This assumes Prometheus stores NS and NHCB (and NH) going forward (for
best case efficiency), but is expected to work for classic mode too with
little overhead (benchmarks will tell us).
