> Solr responses include "QTime", which in retrospect might have been better 
> named "elapsedTime".  We propose adding here a "cpuTime" to return the amount 
> of time consumed by 
> ManagementFactory.getThreadMXBean().[getThreadCpuTime|https://docs.oracle.com/en/java/javase/11/docs/api/java.management/java/lang/management/ThreadMXBean.html]().
>   Unlike QTime, this will need to be aggregated across distributed requests.  
> This work item will only do the aggregation work for distributed search, 
> although it could be extended for other scenarios in future work items.
