Support histogram fields in rate aggregation #62939
Description
#60674 added a rate aggregation to Elasticsearch. It does currently not support histogram fields:
“Field [transaction.duration.histogram] of type [histogram] is not supported for aggregation [rate]”
To use the rate aggregation in the APM app, we'd need support for histogram fields. We currently have a bug which seems like an ideal candidate to fix by using the rate aggregation: elastic/kibana#77474
