> When exposing prometheus metrics with SOLR-10654 exporting metrics was mostly
> straight forward except for query metric quantiles. Things such as average
> request times exists with the current prometheus internal formatters. But
> Dropwizard gauges can have more complex types in their data structures and
> quantiles fell in that bucket so at the time, exporting these quantiles
> wasn't straight forward. I think these metrics would be very beneficial to
> finally add in and export.
