Michael Semb Wever updated CASSANDRA-16371:
-------------------------------------------
    Description: 
Enable the  jenkins [jmh reporting 
plugin|https://plugins.jenkins.io/jmh-report/] and add a jenkins job to run the 
`ant microbench` target.

Patches
 - cassandra-builds: 
https://github.com/apache/cassandra-builds/compare/trunk...thelastpickle:mck/jenkins-microbench
 - cassandra: 
https://github.com/apache/cassandra/compare/trunk...thelastpickle:mck/trunk_jmh_report

Example results are:
 - CI JMH report: 
https://ci-cassandra.apache.org/job/Cassandra-devbranch-microbench/jdk=jdk_11_latest,label=cassandra/1/jmh-run-report/
  (screenshot attached)

The value of these reports is limited, with different hardware jenkins agents 
and two executors on each agent. But visibility from the reports shows what is 
possible, how agents are difficult (and behave under saturation), and when jmh 
classes are broken (there are no unit tests on these benchmark tests).
