Test and Documentation Plan

1) Cassandra builds - https://github.com/ekaterinadimitrova2/cassandra-builds/commit/643c664b2da194bd80131423f27aa7bb38c13499

2) Cassandra - https://github.com/apache/cassandra/compare/trunk...ekaterinadimitrova2:cassandra:18255-trunk

TODO: add JVM args for NetBeans and eclipse tasks (those tasks were working only with JDK8); 

3) CCM - https://github.com/ekaterinadimitrova2/ccm/commit/20a3f6221d950832ebf8a4fe935084d52e6851c4

CircleCI run #2424 looks good - https://app.circleci.com/pipelines/github/ekaterinadimitrova2/cassandra?branch=18255-trunk

I will have to spin also local Jenkins and test. I suspect there should be more places to apply changes to in Cassandra-builds

 

Eclipse and NetBeans JVM args for JDK 11 and 17 will be handled in a separate ticket.

Description

• update Jenkins builds scripts (Cassandra-builds) for trunk to build and run tests only with JDK 11 and JDK 17 - both Jenkins-dev and post-commit
• the JDK11+17 config files and script in cassandra/.circleci should replace the default J8+J11 test config files and script
• Cassandra trunk build.xml and conf files should be updated - JDK8 removed everywhere
• Any tickets blocked on this one and ready to commit should be committed
• Revert this change in CCM - https://github.com/riptano/ccm/commit/6e71061146f7ae67b84ccd2b1d90d7319b640e4c#diff-0999a90fd83b66b6840af0bbd8afd1ebd9648e135b0665692fa0f523325a1058L984
• Docs will be updated later in CASSANDRA-18233

NOTE: Python Upgrade tests were already switched to 11 in this change, so I think there is no other change pending in cassandra-dtest repo
