Make TestCpuTimeSearch cloud flavored, and re-enable distributed test (#3755)
This is a rework of TestCpuTimeSearch SOLR-16986 so it now runs in cloud mode.
For some reasons, the distributed test (with multiple shard) was flaky,
depending on the seed. It is much easier to maintain now it is aligned with
most of multi-shard tests.

> 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.
