Addressing post-merge comments on #6015.

Fixing a few things that might qualify as regressions:

  • After Exponential Histogram support to the Prometheus exporter #6015, we don't ensure that the metric name is sanitized after appending the unit. This means that disallowed characters in the unit can cause errors.
  • We stopped converting unit 1 to ratio in the simple case. I.e. we convert 1{foo} to ratio, but 1 result in null. Not sure why but I think that's wrong.
