> This subtask is to track migrations of Dropwizard instruments to OTEL. Many
> places that initialize these metrics implement SolrMetricProducer. Doing this
> usually involves finding the initialization of these metric, remove
> Dropwizard and replace with the OTEL equivalent instruments using an one of
> the OTEL attributed metric wrappers.
> From dropwizard to OTEL:
> Gauge -> Gauge
> Counter -> Counter
> Histogram -> Histogram
> Meter -> Counter (May also need Histogram or gauges for rates)
> Timer -> Histogram (Use AttributedLongTimer)
