Implement microbench test target type

michaelsembwever · michaelsembwever · commit dfb52e5acc1a · 2026-01-25T18:10:28.000+01:00
Add microbench-test target for quick test run
 Unify declaration and add assertions on target types
 Fix dirname usages for macos
 Parameter for docker_timeout
 Add more jmh class ignores (that are broken)
 Add disableResume() and better host debug to Jenkinsfile

 patch by Mick Semb Wever; reviewed by Dmitry Konstantinov for CASSANDRA-18873
