Additional improvement: use a wait-free logic to return a task or work permit
patch by Dmitry Konstantinov; reviewed by Benedict Elliott Smith for CASSANDRA-21429
The build+test cells run in `ws("workspace/${JOB_NAME}/${BUILD_NUMBER}/${cell.step}/${cell.arch}/jdk-${cell.jdk}/python-${cell.python}")`, so every build writes a new per-build directory.
The `cleanWs()` only cleans the current cell's leaf, and it sat as the last statement in the `ws` block — so any cell hitting error() (failed/timed-out/aborted) exits before reaching it and leaves the full cell's workspace build behind.

Additional fixes
- upgrade ubuntu-test.docker to ubuntu 22.04 (and some small fixes brought forward from CASSANDRA-20997)
- (.jenkins/k8s) changes gke's small node pool from n2-highcpu-8 to e2-highcpu-8 (gke's own pod resources reqs increased)
- (.jenkins/k8s) limit one agent pod per node (when jenkins is deployed in k8s using our helm)
- (.jenkins/k8s) add the cassandra-6.0 job
- pass maven.repo.local sys prop, if set, into accord's gradle build
- check and fail on maven dependencies checksums when downloading
- when on-the-fly building docker images add `--load` (podman compatbility)
- newer python versions can use venv instead of virtualenv
- rename ubuntu2004_test.docker to ubuntu-test.docker (in 5.0)
- (Jenkinsfile) fix retries (which was no longer working when agents/nodes died, since CASSANDRA-20833)
- (Jenkinsfile) @NonCPS where (now) needed
- (Jenkinsfile) fix default value for the branch parameter (after a new helm deploy)
- (.build/run-ci) fix missing parameters on jobs also at helm deploy time
- (.build/run-ci) .git suffixes on repo urls are optional

org.apache.cassandra.db.rows.RangeTombstoneMarker.Merger is allocated on demand
Optional usage in org.apache.cassandra.db.rows.UnfilteredRowIteratorWithLowerBound is replaced with a boolean field
Double in org.apache.cassandra.io.util.CompressedChunkReader#getCrcCheckChance - specialized supplier is used to avoid boxing
Stack - adjust default from 5 to 6 to avoid extra resizings in org.apache.cassandra.db.transform.Stack#resize
EnumSet for CL guardrail in SelectStatement - add a condition to allocate it only if the guardrail is enabled
EnumSet in ResultMetadata - replace it with plain int flags

Current ReadCommand logic returns ArrayCell values, so when we retrieve a cell value as a ByteBuffer we allocate ByteBuffer instances

The validation of snapshot names is turned off by default.
It is controlled by system property cassandra.snapshot.validation which is by default
set to false except 7.0 branch.
When the validation is turned on, the allowed characters are AWS safe characters together
with "+" character. A user can not specify any path separators in snapshot names even if
the validation as such is turned off.

org.apache.cassandra.utils.MergeIterator.Candidate - has Comparator field which is the same for all Candidates under an MergeIterator instance, we can move the field to MergeIterator level. Candidate is 4.8% of all allocations and we can save 20% (~1% of all allocations) of it for JDK 21 with compressed references on.
switch from ArrayList to array in org.apache.cassandra.db.rows.Row.Merger
The ArrayList iterator costs 0.72% and BulkIterator.Adapter costs 0.35%. So, in total we can save here ~1% of total allocations.

Set 1 thread and 1 second for the measurement iteration (note: it is a smoke test only, we do not analyze results from such short measurements)
Exclude some options for heavy benchmarks by default
Shutdown all threads once JMH test is completed to avoid awaiting of a forked JVM till timeout at the end
