Changed the Transactional Trait:
* new interface should fit better for Coherence or Hazelcast
* better suited for transactions spanning multiple resources (caches)
Coherence transactions implementation
* API should be OK, but in fact it's not working (throwing exceptions)
* committing implementation in order to not block further development, but the trait is disabled (commented out)
Enabling POF (by default) for Coherence
* POF should provide better performance than Java serialization
* Utils: conf/ directories should be on classpath sooner than library jars
Implemented querying in Hazelcast 3
Removed remoting-jmx as this was causing marshalling conflicts with Infinispan
Number converter: negative numbers pattern
IterationsStats need to be static.
* Reporter properties should by specified in camelCaseNotation, not in xml-way
* Reporters should be created before the test in order to fail soon if there's some typo
