- consumer and producer threads wait signal without acquiring the lock first
- lock owners may prepare more work than they need, moving some dynamically-adjusted portion of the work from the prioritised lock-managed structures onto a non-blocking queue, so that other threads may consume work from there; the portion is continually micro-adjusted to target some available work whenever the lock is acquired.
- adopts/supports some features of the SEPExecutor:
- threads may auto-adjust the number of running threads based on how much time is collectively spent waiting, to minimise time spent signalling
- consumers may (timed-sleep) poll rather than await a signal, reducing the number of kernel interactions needed; relying on the auto-adjustment to bound the time the scheduler spends waking threads with no work to do
Also Fix:
- Client Result should not be persisted or included in Command object at any time

This is the continuation of CASSANDRA-21319 to make branching of cassandra-6.0 done.
The change in .build/run-ci will start to route jobs to cassandra-6.0 pipeline in pre-ci.

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

This is backport of CASSANDRA-18875 to 5.0 where we upgrade 2.1 of snakeyaml and bump jackson-dataformat-yaml to 2.19.2.
The change in trunk (5.1) is about excluding Jackson dependencies from wiremock so 2.19.2 of Jackson is used everywhere in test as well,
otherwise there would be Jackson annotations of 2.13.4 used.

Replace io.airlift:airline dependency with info.picocli:picocli across
all nodetool command implementations. This migration includes:
- Convert 160+ nodetool command classes from airline to picocli
- Add AbstractCommand base class for commands and utility methods
- Add NodetoolCommand top-level class for the cli utility
- Update all command classes to use @Command, @Option, and @Parameters
- Add plain text files to test command help output
- Add mock test classes for improved test coverage and parse validation
- Modify test infrastructure to work with picocli-based commands
- Add new layouts for cli formatting to preserve backwards compatibility
The migration maintains backward compatibility while providing improved
command-line parsing, better help system, and more robust argument
validation through picocli enhanced features.

As part of a broader effort to decouple java driver code from the
server code, this moves sstableloader to its own tools directory.
As sstableloader is also used as a library (CASSANDRA-10637), added
a new artifact 'cassandra-sstableloader' that will get deployed to
maven along with 'cassandra-all'.
While I expect this is likely a niche use case, this will allow users
to continue using BulkExport as a library.
Moves sstableloader-specific targets to its own build.xml in
tools/sstableloader/build.xml.
Also updates IDE project files and circleci to utilize new
sstableloader-specific targets.
