bq. We need to also consider how to merge distributed debug info (and add more
info about the distributed phase as well). Given this, (2) may be simpler
(adding directly to facet response) as we already have a framework for merging.
(From SOLR-8228)
Probably better to use a separate merger to merge facet telemetry information.
The main reason is that facet telemetry merging may be different to facet
result merging. For example, some fields in facet telemetry are not merged. In
addition, the merged telemetry need to contain both merged numbers and
telemetry from each shards.

> This is to merge facet telemetry information from shards together. Here is
> the way to merge different fields in facet telemetry.
> 1. elapse: sum of elapse fields in shard telemetry
> 2. domainSize: sum
> 3. numBuckets: sum
