Statistics for stress tests where the performance is expected to (not) change during the test execution
Adapting API used for Debugable to Infinispan 6.0
JGroups 3.5.x plugin
Fix: Remove must be in different TX than Put
* otherwise we may encounter a long window when one entry is already removed but the other is not inserted yet
* SimpleStatistics can compute variance (online algorithm)
* Added confidence intervals and other statistical variables to the report
* Sum up in report (AVG row) is now computed using statistics merging, not as average of the other rows
New HTML report aggregating all the charts and data from CSV files
* More ways of retrieving data from SimpleStatistics
* Fixed bugs in HistogramStatistics, Table...
* Removed unused code (ChartGen, AbstractChartGen, PutGetChartGenerator...)
* chart.sh -> report.sh: generates whole report, not just single chart
HTML report improvements
* expandable per-node statistics, different results detection (red background)
* parsing of the CSV files is more robust
* Standard sample deviation instead of standard error of mean
* Alt names for histograms
Fix an issue in populateGraph() that could cause an
IndexOutOfBoundsException

It's possible that one node in the cluster collected more JVMMonitor
items than another node. In this case, the extra items are ignored.
Trivial bug fix - conversion between milliseconds and nanoseconds.
* JGroupsWrapper allows setting of the OOB flag
* ~default JGroups configurations (threadpool settings changed)
Added anycasting and implemented remove operation in JGroupsWrapper
CacheWrapper (BasicOperations) API supports local/global clear
* ClearClusterStage uses local clear on each node by default
Fixes for delayed removes
When request in tx throws exception, the tx should be ended immediatelly
Changes in stressor related with soak-testing
* Logic can react upon request execution failure
* ChangingSetOperationLogic may use numBytes instead of numEntries to specify data load
** this makes sense when using entrySize with multiple values
* Configurable entry lifespan for fixedKeys=false settings
* TimeConverter accepts hours and days
