Revised the POM files
* all external dependencies in plugins should be <optional>true</optional>
* radargun dependencies don't need the exclusions
* brought some query dependencies (needed in future commits)
StressTest: option for fixed period requests (instead of executing them at maximum pace)
Properties can be defined using nested XML
* Works for stages
* Still TODO for services and reporters
Querying using DSL (removed old query support)
* you can form any condition/projection/sort etc. in the QueryStage
* example objects: TextObject and NumberObject enabled for both Lucene & Protobuf queries
* example data generators
Minor fixes
Minor help correction in dist.sh
Query: contains condition
Moved generally usable converters into org.radargun.utils
Simple stage allowing to execute custom command on the slaves
Added stress-test.seed to fix initial data in the cache
* this is useful when we want to use stress-test just to preload data for query
JGroups dumper can be started before cache manager
Moved JPA to subdirectory specific/
Moved generators to core
* use reflection to get the class in the same way as JPA generators
* Changed Queryable.list() -> Queryable.values()
* the check for identical results of query from all slaves is off by default
Minor fixes
Implemented querying functionality for Coherence
Added plugin for Coherence 12.x
