David Smiley closed SOLR-16986.
-------------------------------

Need to resolve this against 9.5 as 9.5 was released.

> 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.
